ABSTRACT In order to research vertical bedrock deformations in the Olkiluoto area, Posiva Oy and the Finnish Geodetic Institute began monitoring with precise levelling in 2003. At the moment, the measuring plan includes a loop between the monitoring GPS stations around the island, a levelling line from the island to the mainland, levelling loops to ONKALO, the final disposal site, and VLJ, the low and intermediate level waste repository there. The levelling to the mainland has been performed every fourth year and the levelling of the GPS stations every second year. The micro loops (ONKALO and VLJ) have been measured annually. In this report, we use three-step method to research a vertical deformation of the Olkiluoto area. Firstly, the linear deformation rate in the area has been determined by the least squares adjustment of the levelling data. It varies from –0.2 mm/yr to +0.2 mm/yr. Secondly, local deformations have been analysed by comparing the height differences for different years. In this comparison a starting value for the yearly adjustment has been corrected for land uplift. Using this method the elevation changes are relative to the whole network. For a fixed benchmark, we correct its yearly deformation. Thirdly, the fault lines have been analysed by comparing the elevation changes between the successive benchmarks from one observation epoch to another. The results show that ONKALO and Lapijoki are in the subsidence area of the network, and VLJ has small uplift rate. On the island some deformations exist, but elevation difference from 2003 to 2011 is less than one millimetre at every benchmarks. The measurements in the Lapijoki-Olkiluoto line in 2003, 2007 and 2011 show that linear elevation change between the mainland and Olkiluoto island is a little since 2003. The elevation differences, from Olkiluoto to Lapijoki, measured in 2003 and 2011 differ less than one millimetre each other, but the 2007 observation differs three millimetres from the other measurements. Keywords: Deformation of bedrock, precise levelling, vertical control.

Olkiluodon kallioperän muodonmuutosten analyysi tarkkavaaitusten avulla TIIVISTELMÄ Geodeettinen laitos perusti Olkiluodon GPS-verkon 1994 ja suoritti ensimmäiset tarkkavaaitukset syksyllä 2003. Tällöin mitattiin GPS-verkko ja vaaituslinja Lapijoki-Olkiluoto. Linja liittää Olkiluodon alueen tarkkavaaitusverkkoon ja mahdollistaa Olkiluodon saaren ja mantereen välisen muutoksen seurannan. Mittaukset linjalla Lapijoki-Olkiluoto päätettiin suorittaa joka neljäs vuosi ja GPS-verkossa joka toinen vuosi. Syksyllä 2006 ONKALOn ja VLJ-luolan yläpuolelle perustettiin mikrosilmukat. Nämä vaaitussilmukat on mitattu vuosittain. Tässä raportissa analysoidaan Olkiluodon alueen kallioperän deformaatiota käyttäen vuosien 2003-2011 havaintoja. Kiintopisteiden maannousunopeudet on laskettu käyttäen pienimmän neliösumman tekniikkaa. Maannousunopeuksia käyttäen on määritetty deformaatiomalli eli kunkin pisteen liike suhteessa muihin pisteisiin. Olkiluodon saarella painumisalue on ONKA-LOn ja GPS-asema 13:n ympäristössä. Lisäksi Lapijoen alueella maannousunopeus on hitaampaa kuin alueella keskimäärin. Olkiluodon salmen saaren puoleisella alueella maannousunopeus on suurempi kuin mantereen puolella. VLJ-luolan alue kuuluu keskimääräistä nopemman maannousun alueelle. Maannousunopeuden muutoksen tutki-minen vaatii pidemmän vaaitushistorian. Nyt yksittäisten pisteiden deformaatiot domi-noivat puolitetun aikahistorian ratkaisua, eikä luotettavaa arviota maannousunopeuden muutoksesta pystytä kertomaan. Kiintopisteiden korkeus mittausajankohtana on määritty käyttäen kiinnitettyjen pistei-den deformaationopeuksia. Määrityksen perusajatuksena on kiintopisteiden korkeuksien summan vakiona pysyminen vuosien ajan. Koska eri vuosien kiintopisteiden joukot eivät ole identtisiä, niin suoraan ei voida kiinnittää korkeussummaa vakioksi. Korkeudet on ratkaistu käyttäen yhtä kiinnitettyä pistettä yhtenäisessä verkon osassa. Eniten käytetty piste on 03216. Sen deformaatio suhteessa muihin pisteisiin on –0.084 mm/vuodessa. Näin ollen kunkin vuoden kiinnitetty arvo on tätä deformaatiota pie-nempi kuin edellisenä vuonna. Tämän kaltainen tasoitusratkaisu leikkaa suurimpia deformaatioarvoja. Esimerkiksi mittaushistorian aikana piste 03216 on painunut 0.7 mm ja GPS6 on vastaavasti noussut 0.9 mm suhteessa koko alueeseen. Tämä tekniikka antaa todenmukaisemman kuvan deformaatiotilanteesta, kuin se että ajateltaisiin deformaation kohdistuneen ainoastaan pisteeseen GPS6, joka olisi noussut 1.6 mm. Itseasiassa Olkiluodon saarella kiintopisteiden korkeuksien poikkeamat vuonna 2011 ovat alle millimetrin vuoden 2003 korkeuksista. Kallioperän paikallista deformaatiota on tutkittu vertailemalla kiintopistevälin korkeuk-sien muuttumista eri vuosien mittausten välillä. Liikkeiden merkittävyys riippuu matkan pituudesta, mittauksen tarkkuudesta ja tietenkin korkeuserosta eri vuosien välillä. Merkittävimmät poikkeavan liikkeen pisteet ovat 06220 (ONKALO), 03211 (Olki-luodon salmi) ja GPS9 (VLJ) ja saaren lounaisosassa oleva GPS13. Avainsanat: Kallioperän deformaatio, tarkkavaaitus, korkeuskontrolli.

1 INTRODUCTION

Researching of bedrock deformation is a part of rock mechanics monitoring in the Olkiluoto area (Posiva 2012). Important locations are a final disposal site of spent nuclear fuel (ONKALO) and a low and intermediate level waste repository (VLJ). The levelling network has micro loops for the deformation monitoring of ONKALO and VLJ. Other parts of the network monitor large-scale deformation in the island itself and its deformation relative to the mainland. Deformation analysis is based on a three-step method (Saaranen et al. 2013). Firstly, the kinematic model as a solution for the least squares adjustment is determined. Secondly, the elevations of the benchmarks for different years are computed. The starting values for the adjustments are corrected with the deformation rate, which was determined in the first step, and thus the heights are relative to the mean deformation of the research area. Thirdly, using a statistical test, probable fault lines are sought. The deformation of the Olkiluoto–Lapijoki line, ONKALO and the GPS network is presented relative to the deformation of the whole research area. VLJ and the Olkiluoto strait, which are small research networks, are presented relative to one fixed benchmark of the network. For the GPS antenna deformation rates we prefer the movement of the control marks. Measurements for the antenna platform levels need an extra bolt and performance of the measurement is more complicated, due to the heights of the GPS pillars. Since 2003, vertical deformation of the Olkiluoto area has been studied using precise levelling. Results of the measurements have been published every second year in the Posiva levelling working reports by Lehmuskoski (2004, 2006, 2008 and 2010) and Saaranen et al. (2012). In this report, a summary of deformation is presented.

2 DESCRIPTION OF THE LEVELLING WORK

All important areas in Olkiluoto have been connected by the levelling network (Figure1). During the years, it has been extended. In the beginning, in autumn 2003, it included the GPS network loops and the Olkiluoto–Lapijoki line, which connects Olkiluoto to the national precise levelling network in Lapijoki. The line gives information about the movement of the Olkiluoto area relative to the mainland. It was decided that this line should be surveyed every fourth year and the GPS network every two years (Table 1). In 2005, the antenna platforms of the GPS stations were added to the measuring plan. In 2006, the network was extended when new levelling loops were established and levelled to ONKALO and VLJ. Since 2007, the lines at Olkiluoto strait, ONKALO and VLJ have been levelled annually. All benchmarks were established on bedrock.

The extension of the levelling network was based on the observed deformation. In the GPS network loop, height change of benchmarks GPS6 and GPS9 was more than one millimetre relative to other benchmarks from 2003 to 2005 (Lehmuskoski 2006). So, new loops were established onto the ONKALO and VLJ. In 2007, it was noticed that in the loop ONKALO benchmark no. 06220 was one millimetre higher than a year ago (Lehmuskoski 2008). Two new benchmarks were established near the benchmark in 2008. The problem area over the Olkiluoto strait was found out in 2007. The height difference of the benchmarks 03208 and 03211 changed 1.91 mm from 2003 to 2007 (Lehmuskoski 2008). The analysis of the fault lines and local deformations is presented in Chapters 5 and 6. The benchmarks and their geographical coordinates longitude (°) and latitude (°) are presented in Appendix I. Coordinates have been observed by Garmin eTrex GPS receiver. Accuracy of the coordinates can be some metres. The levelling observations are presented in Appendix II and special measurements for the GPS antenna platforms in Appendix IV. Observers from the Finnish Geodetic Institute have performed levelling observations. Assisting persons were employed by Posiva. There are five persons in a levelling team: an observer, two people taking care of levelling rods, one person measuring distance on the levelling line and one person, with an umbrella, protecting an instrument against rain and disturbing sunlight (Figure 2). Levelling teams have established the benchmarks. There are five digits in a benchmark number. First two numbers represent the year, when the benchmark was established. For example, benchmark no. 06220 was established in 2006. Benchmark intervals have been measured in both directions in order to minimise systematic errors, which are typical for levelling measurements (Takalo et al. 2002). Every levelling observation is therefore based on at least two measurements. In the adjustments average values have been used. Accuracy of the levellings has been around 0.2mm/√km (Table 7), with this accuracy the closing error of a hundred kilometres long levelling loop would be 2 millimetres. Equipment of a levelling team were according to a standard precise levelling procedure. The digital level Zeiss DiNi12 no. 320243 was used as a levelling instrument. Only exception was the last week of the 2003 observations, when the level no. 320015 was used. Usually rod bases were steel plates (turtles). Sometimes wedges and spikes were used. Sighting distances were measured using Rollfix Super measuring wheel. The rods with a bar-code scale and an aluminium frame were used. One-metre rod Zeiss Nedo LD11 no. 11640 was used in the GPS antenna platform measurements, but during a normal levelling the three-metre LD13 rods 13926 and 14092 were used. The calibrations of the levelling rods were carried out before and after the field season, using the FGI vertical rod comparator; Takalo (1999), Takalo and Rouhiainen (2002). The scale corrections and thermal expansion coefficients are presented in the Tables 2 and 3.Temperature readings were used to correct the rod length change due to changing temperature conditions. The distances between the single lines of a rod scale were

measured using the laser interferometer HP 5529A with a laser head HP 5519A no. 3627A00665 and the COHU CCD-camera with an area sensor. Positions of every bar code were determined by measuring distances from the defined beginning graduation line. The nominal and true positions were compared and the results were reduced to the temperature of 20 °C. The scale factor was determined with a linear regression. Standard uncertainty in a rod calibration is 1.0 µm/m. The linear thermal expansion coefficient of a invar rod was determined using the vertical laser rod comparator of the FGI. The length of the invar band was measured in at temperatures in a cycle of 20° - 10° - 30 °C. Vaisala QLI50 thermo/humi cap HMP35D no. S0920037 and pressure unit PTB100A no. S0430008 were used to determine ambient temperature, relative humidity and atmospheric pressure. The procedures meet the requirements of ISO 9001 and ISO 17025 quality standards. Table 2.

Refraction correction was computed with the Kukkamäki formula (Hytönen 1967). In the correction, temperature difference between 2.5 m and 0.5 m above the ground is needed. It was recorded during the levelling, with a Fluke 54 II thermometer at one-minute intervals. The refraction correction, in mm, for one setup is

All measurements of a single line or a loop have been collected to a line paper. In a line paper can be seen computed corrections and height differences in geopotential units, which have been used in the determination of N2000 height for a fixed benchmark. Line papers are presented in the Posiva levelling working reports.

3 DETERMINATION OF THE KINEMATIC DEFORMATION MODEL

The deformation was solved with the help of the least squares estimation of the adjusted height differences. The applied method is the same as in the land uplift determination of repeated precise levellings in Finland (Mäkinen and Saaranen 1998). In the adjustment, we have 49 benchmarks and 243 observations (Appendix I and II). In the model, we determine the uplift rates (mm/yr) and the heights in the adjustment epoch of 2003.7, which is the epoch of the first performed levelling. The observation equation is

y(i,j,k) = h(j,2003.7) – h(i,2003.7) + [h(j) – h(i)][t i, j, k – 2003.7] + e(i,j,k), (3) where y(i, j, k) is the observed height difference between benchmarks i and j in the observation epoch t(i, j, k), that is equal to the elevation difference of the benchmarks in the adjustment epoch and an unknown land uplift between the observation and adjustment epochs. Notations for the benchmark heights in the adjustment epoch are h(i, 2003.7) and h(j, 2003.7). The time derivatives of heights h(j) and h(i) are the land uplift rates, and e(i, j, k) is the residual of measurement. Because the levelling produces only height and land uplift differences, we use fixed height and land uplift values for the benchmark no. 03216. The height 9.870 m is in the new Finnish height system N2000; Lehmuskoski et al. (2008) and Saaranen et. al (2006). The starting value for the land uplift values, 5.439 mm/yr, is taken from the Nordic land uplift model NKG2005LU (Ågren and Svensson 2007). The model is based on Vestol’s empirical model and Lambeck’s geophysical model, Vestøl (2007) and Lambeck et al. (1998). All repeated Nordic precise levellings, data from the permanent GPS stations, and observation series of tide gauges in 1892–1991 are included in the Vestøl’s model. Lambeck’s empirical data include tide gauge data in the territory of the Baltic Sea and information about the tilting of the water level of the biggest lakes in Sweden and Finland. In our deformation analysis, we do not use the land uplift rates relative to mean sea level, since we are more interested in researching deformation differences in the area. So the average uplift, 5.523 mm/yr, has been removed from the uplift rates in Figure 3. The kinematic solution shows, that a local subsidence area includes the ONKALO loop. The VLJ loop is in the rising area. Its mean deformation rate is +0.05 mm/yr. ONKALO has an average deformation rate of –0.10 mm/yr, and the Olkiluoto strait has a small subsidence value of –0.03 mm/yr. In the Olkiluoto strait area benchmarks on the island are rising and on the other side of the strait they have opposite deformation. The Lapijoki area has a deformation rate similar to that of ONKALO, i.e. –0.11 mm/yr. This rate is based on the average value of the three easternmost benchmarks of the Olkiluoto–Lapijoki line.

Figure 3. The deformation rates (mm/yr) when the average land uplift has been removed. In the Olkiluoto-Lapijoki line deformation is based on three levellings, and thus the deformation rates are less reliable than on the island, where exist more levellings in small levelling loops. The standard deviation of the land uplift rate at Lapijoki is about ±0.3 mm/yr and on the island ±0.1 mm/yr. The standard deviation is relative to the fixed benchmark no. 03216. The complete list of the adjustment is presented in Appendix I. In the list can be found the land uplift values which are more or less in the NKG2005LU model, and the deformation of the benchmarks relative to the other benchmarks.

3.1 Land uplift rate change on the island

In this section we research deformation rate change on the island. We compare land uplift rates which are based on observations from 2003 to 2007 for the model from 2007 to 2001 observations (Table 4). These comparisons are correlated, both have observation from the year 2007. Deformation between the island and Lapijoki area is discussed in Section 6.1. The most significant land uplift rate change happens with the ONKALO benchmark no. 06220. The movement of this benchmark is independent from other benchmarks in vicinity. Detailed analysis of this movement is presented in Section 6.4.

Remarkable change happens in the loop VLJ due to the fact that it is connected to the network using the control marks of GPS9. From 2006 to 2007, GPS9 had negative deformation value, but from 2003 to 2007, it has a small linear rate. As a combination of these, we get large uplift rate value for the benchmarks in the loop VLJ. In the model UPL1, at the benchmark 06220 and the benchmarks in VLJ, uplift rate is based on only one year deformation, from 2006 to 2007. Table 4.

4 ELEVATIONS FOR THE DIFFERENT YEARS

In this report we research deformation, if possible, relative to the whole levelling field. In a computation method we correct deformation rate of a fixed benchmark. We use three different benchmarks (Table 5). The most important benchmark is 03216. It is the fixed benchmark in the Olkiluoto-Lapijoki line, Olkiluoto GPS network (OLKIA, OLKIB), and the loop ONKALO. Benchmark no. 06214 has been used in the loop VLJ, if it was measured without a connection to 03216. Third fixed benchmark is 03208, which was used in the Olkiluoto strait computations. In the deformation analysis in Chapter 6, we compare only the elevations which were measured in the continuous network i.e. elevations were adjusted using a single fixed benchmark and both benchmarks were included into the same network. For example we study deformation between the benchmarks 03216 and 03208 only using observations from 2003, 2007 and 2011, when these benchmarks were connected by the levelling observations in the campaingns. All measurements and computations have been presented in the Posiva levelling working reports. We do not make any new adjustments for the elevation determinations. We only correct starting value (Table 6), so that height differences between benchmarks remain the same in an single year, but the elevations can have a constant value difference in comparison with the previous values in the Posiva levelling reports. Table 5. Fixed benchmarks in the adjustments and their deformation rate relative to the levelling network.

Fixed benchmark for the elevations is the benchmark no. 03216, with the elevation 9.870 m in 2003.7. The benchmark is located in Olkiluoto island near ONKALO. Deformation values for the fixed benchmarks are in Table 5. These values are used in computation of the fixed values for the different years. Yearly elevations of the benchmarks are presented in Appendix III.

5 THE ANALYSIS OF THE FAULT LINES

In our case we are interested in dip-slip faults, in which the relative motion of the bedrock on each side of the fault line happens in a vertical direction. The problem has been studied by comparing the elevation changes of the successive benchmarks on a levelling line. We use a simple method, which is presented in Lehmuskoski (2006). Complete results of the fault line analysis is presented in Appendix V. The uncertainty of measurement in levelling is relative to the measured distance. The smaller the levelled distance and its uncertainty are, the smaller the movements that can be reliably detected. The standard deviations for the yearly levellings are presented in Table 7. The standard deviations of the levelling in 2010 and 2011 are from the levelling network adjustments (Saaranen et al. 2012). For the previous levelling values were estimated by the Formula 4. (Kääriäinen 1966)

where n = number of the loops, φi = closing error of the loop, Fi = circumference of the loop, φe = closing error of the circumference of the network and Fe = length of the circumference of the network. Table 7. Standard deviations for the levelling campaigns (mm/√km).

When we compare the results of two campaigns, the standard deviation of their difference is estimated by the formula

The critical value can be considered significant, when the change of the elevation is more than threefold of the standard deviation of the discrepancy:

S=[y(i,j,k1)–y(i,j,k2)]/[ , (6) In the formula (4), y(i,j,k1) is the observed height difference in the year k1, τ is the standard deviation, and , is the length, in kilometres, of the levelling line between the benchmarks i and j. The deformation can be considered significant if the significance level Sτ >3. In other words, the change in the height difference is more than three times the standard deviation of the difference. For instance, if the elevation difference of one kilometre long interval has changed from 2003 to 2011 more than 0.75 mm, the change can be considered to be significant. Table 9 shows the most probable fault lines. In the table the most significant deformations are presented, so some benchmark intervals are several times. For example the deformations from the benchmark no. 06220 to 06219 and 06221 are significant in many comparisons. From the table we can see that the movement of the benchmark no. 06220 from 2006 to 2009 differs from the movement of other benchmarks in the vicinity. The locations of the fault lines is presented in Figure 4. Table 9. The most significant deformations inside the benchmark intervals in the Olkiluoto research network.

6 LOCAL DEFORMATIONS

The local deformation in the different parts of the network is presented in this chapter. In the comparisons we use the elevations, which are presented in the Appendix III. Firstly we present results from the island to the mainland of Finland.

6.1 Lapijoki-Olkiluoto

The line from Olkiluoto to Lapijoki begins from the benchmark no. 03216, and the nodal point in Lapijoki is no. 51310 (Figure 5). That nodal point belongs to the network of the Finnish precise levelling network. The deformation rate difference between the nodal point on the Olkiluoto island and the Lapijoki area is small (Figure 3), and it is less than standard deviation of the uplift rate. The most significant fault line is located over Olkiluoto strait from benchmark no. 03208 to 03211 (Table 10), which is studied in Chapter 6.2. Table 10. The most significant benchmark interval deformations in the Olkiluoto-Lapijoki line.

Figure 5. The benchmarks in the Olkiluoto-Lapijoki line, which are used in this report. Levelling line Lapijoki-Olkiluoto has been measured every fourth year. Levelling results measured in 2003 and 2011 indicate that Olkiluoto island is not uplifting or going down relative to Lapijoki. Without land uplift correction difference is only 0.27 mm. From NKG2005 land uplift model (Ågren and Svensson, 2007) we get that during one year land uplift at Olkiluoto is 0.17 mm more than at Lapijoki. Figure 6 shows a comparison between three levellings. The small uplift difference is a result of three measurements, which have interesting differences. It can be seen that the differences between the 2007 measurement and the other measurements in 2003 and in 2011 is about three millimetres. For the heights this means that, relative to the fixed benchmark no. 03216 on the island, in 2007 Lapijoki benchmark was three millimetres lower than it was in 2003. Between 2007 and 2011, the deformation had opposite direction. There are two positive deformation anomalies in the line Olkiluoto–Lapijoki Figure 6. The benchmarks no. 03204 and no. 03206 have been raised by about 1 mm from 2003 to 2011. These benchmarks have anomalous uplift values, more than +0.10 mm/yr. The benchmark between these two, the benchmark no. 03205, has a small subsidence value, which stands out, in Figure 3 and Figure 5, as a distinctive curve. The algorithm for the contours is presented in Smith and Wessel (1990). This kind of surface is not the best possible when we have only one line, like in our case, in that part of the levelling network. Nevertheless, the result nicely shows that the deformation rate is changing between the positive and negative values in the Olkiluoto–Lapijoki line.

Figure 6. The elevation changes in the Olkiluoto-Lapijoki line from 2003 to 2007 and 2011 (in millimetres). The starting benchmark, the benchmark no. 03216, is in the subsidence area of the network. Only the benchmarks which belong to all the campaigns are presented.

6.2 Olkiluoto strait

Olkiluoto strait is an eight hundred metres long benchmark interval, which connects the island to the mainland. Land uplift rates on the island side of the strait are higher than on the mainland side (Figure 7). From 2003 to 2007, the benchmark no. 03208 on the Olkiluoto island had lifted 1.91 mm up compared to the benchmark no. 03211 on the mainland. To study this interval more precisely some new benchmarks were established in 2008, and it has been measured annually since 2007. The elevation change of the interval has stabilised since 2007, and in 2011 height difference was close to that of 2007. The deformation over the Olkiluoto strait is presented in Figure 8. The height differences relative to the benchmark no. 03208 were computed for every benchmark and for every year. The deformation between the years was then determined by removing the benchmarks height in 2008. If we compare the benchmark no. 03208 to the other benchmarks on the island, we observe no remarkable deformation. For example, the height changes between the benchmark no. 03208 and the benchmarks no. 04004 and no. 08203 in the vicinity are about 0.1 mm during the observation period. The latest deformation is in a short interval between the benchmarks 03211 and 04005. In 2011 height difference is about a half millimetre more than in the previous measurements. It can be seen from Figure 8, that elevation of 04005 has changed about a half millimetre from 2010 to 2011, but during that time, 03211 was stable.

24

During the year 2004, some new benchmarks were established without network measurements. We study deformation using the adjusted elevations relative to fixed benchmarks, so we skip observations made in 2004 from the Figure 8. For example in spring, benchmark no. 04004 was added to the network with the observation from 03208. Height difference was 279.88 mm. Later this height difference has been about 279.2 mm, like in 2010. The land uplift rate of the benchmark 04004 is smaller than 03208, due to the 2004 observation in the land uplift model computation (Figure 7). According to Lehmuskoski (2010), the 2004 measurement was levelled 31st of March and later measurements have been done in late autumn and the reason for the elevation difference can be the different temperature of bedrock in March and September, estimated to be about 15 °C in the vicinity of the surface of the bedrock (Lehmuskoski et al. 2006).

Figure 7. Line Olkiluoto strait has six benchmarks. At the moment most active part of the line is 04005-03211.

Benchmarks no. 04004 and no. 08203 are removed from the comparison. Their movements relative to 03208 are about 0.1 mm in the comparison years.

6.3 Deformation of the island: OLKIA and OLKIB

Levellings around the island are included in the loops OLKIA and OLKIB. There are two micro loops on the island, ONKALO and VLJ, these loops will be discussed in the chapters 6.4 and 6.5. The local stability of the GPS stations will be discussed in chapter 6.6. Table 11. The most significant benchmark interval deformations in the GPS network loop (OLKIA).

Deformation happens in the loop OLKIA (Figure 9). Connection to the GPS station GPS3, OLKIB, has been stable during the years. The most interesting deformations are related to GPS stations GPS6, GPS9 and GPS13. For example, between 2003 and 2005, the elevations of the GPS stations GPS6 and GPS9 raised more than one millimetre relative to levelling research network (Figure 10). GPS13 has an interesting elevation

minimum in 2009. Elevation was 0.7 mm lower than two years before, but in 2011 it was almost at the same level like in 2007. According to Lehmuskoski (2010), deformations of GPS6, in 2003-2009, and GPS13, in 2007-2009, were based on large construction works near these stations, parking area around GPS6 and nuclear power station of Olkiluoto 3 near GPS13. The fault line list (Table 11) is dominated by the short measurements between the control marks of the GPS stations.

The benchmark no. 03216 has been fixed in the yearly adjustments with a linear subsidence rate. The deformation of GPS13 is relative to the year 2005.

6.4 Micro loop ONKALO

ONKALO is in the subsidence area, but the benchmark 06220 has an unique deformation rate, which seems to be a very local phenomenon (Figure 11). Its neighboring benchmarks are stable, but the observations from the benchmark no. 06220 are in the fault line list (Table 12). It can be seen in Figure 12, that mostly deformation happened between 2006 and 2007. Since then it has been stable relative to the levelling network. Of course movement relative to 03216 continued to rise after 2007, because 03216 has a negative deformation rate. In order to research deformation of 06220, benchmarks 08201 and 08202 were added in 2008, but after some observation years no significant deformation has been found. The observations show that benchmarks 08201 and 08202 do not belong to the same rising area. During the last years, no any active crustal deformation happens over ONKALO. All the comparisons between the 2009, 2010 and 2011 observations were below statistical significant level. The fixed benchmark 03216 seems to have a peak elevation in 2010 (Fig 12). In the figure it can be seen, that the other benchmarks in the ONKALO loop have local minimum elevation in 2010. It is more likely that the simultaneous deformation does not exist and thus the elevation minimum is based on the positive deformation of the starting value benchmark 03216.

6.5 Micro Loop VLJ

In the VLJ loop, the most active deformation is related to the control benchmarks of GPS9 (Table 13 and Figure 14). This movement does not have any systematic nature. The deformation is like the other benchmarks, except for 06213. It is interesting that 06213 has a linear subsidence deformation relative to the other benchmarks in the VLJ loop (Figure 13 and Figure 14). Table 13.

6.6 GPS antenna platform measurements

The stability of the GPS pillars was controlled from 2005 to 2011. At the moment, the GPS stations operate continuously, but earlier the 24-hour-long sessions were observed annually in spring and autumn. Between the sessions, antenna platforms were available for the levelling measurements. The control benchmarks of the GPS stations were included in the measuring plan when the GPS network was levelled for the first time in 2003. Since 2005, the elevations of the GPS antenna platform levels have been measured. During the observation, a small one-metre-long rod is placed on a bolt fastened on a GPS antenna platform (Figure 15). One assistant has a three-metre rod on a control benchmark, as in an ordinary levelling, and another assistant is standing on a ladder (Figure 16). The control benchmarks are at the distance of about 10 metres from the GPS stations. Having been established on the same bedrock block, the GPS stations should have the same uplift rate as the control benchmarks. The difference in the uplift rates is presented in the Table 14. The results are based on six years of monitoring and included four levelling campaigns.

In 2011, there were 19 GPS stations in the Olkiluoto GPS network and the stations with repeated levellings were GPS2, GPS3, GPS4, GPS6, GPS7, GPS8, GPS9 and GPS13. The errors due to a special extra bolt on an antenna platform, and a zero error error of a rod was corrected before the analysis. The levelling was focused on a bolt on an antenna platform. To obtain the elevation of the antenna platform, the height of the bolt have to reduce from the levelling results. There are two extra bolts “A” and “B”, which were used. For example, in 2011, the bolt “A” was used, and its height was 19,912 mm. A levelling rod can have so called zero point error. It has been eliminated using the same rod on a benchmark at the starting and ending benchmarks. In the GPS platform measurements we use different rods, so the zero point error have to correct. In 2011, it was eliminated by the observing method. In the previous years, the zero error was determined and corrected afterwards. In Appendix IV, is the list of observations between the GPS antenna platforms and control marks, and the used corrections for the extra bolt height and the zero point correction of the rod. When the elevations of GPS points were compared, we used the mean of their control mark pair with the exceptions of GPS2 and GPS4, whose other pair had been damaged. The control mark GPS2B was measured in 2011. It was found to be damaged by a working machine in 2009 so it was not used in the comparison with the previous measurements. A new control mark GPS4C for GPS4, was established in 2011.

Local stabilitity of the GPS pillars is good. In Table 14, the summary of the deformations between the GPS pillars and their control marks is presented. Maximum difference between the observations of different years is 0.26 mm at the GPS4, but it does not have any linear effect. Deformation difference between the pillar and its control marks is only +0.03 mm/yr. In the table is the average levelled distance, which is based on the distances from an instrument to a rod on GPS pillar and rod on a control mark. Land uplift rates are relative to the mean sea level due to the NKG2005 rate as a fixed value. In order to compute the land uplift relative to mass centre of the earth, the sea level rise 1.32 mm/yr and geoid rise, which is 6% of the uplift rate, have to add the uplift rates in the Table 14. Land uplift rates for the control benchmarks are from the table of Appendix I. This kinematic solution has been computed without GPS platform measurements. Deformation rate difference between the control benchmarks and the GPS stations were determined by the different least squares solution which included not only levelling observations (Appendix II), but also GPS platform observations (Appendix IV). The land uplift rate solutions for the contol benchmarks with and without the GPS platform measurements, differ less than 0.01 mm/yr. In the future, the platform levels will have continuously operating GPS receivers. So, new GPS platform measurements will not be performed for those GPS stations. Table 14.

7 SUMMARY

The precise levellings in Olkiluoto were started in autumn 2003. Deformation results have been reported every second year. This report deals with a deformation based on the measurements from 2003 to 2011. Observation material includes the measurements of GPS network and Lapijoki-Olkiluoto line, from the Olkiluoto island to the precise levelling network of Finland, and the micro loops upon ONKALO and VLJ. The deformation in the Olkiluoto area was analysed using a kinematic deformation solution and heights which had been computed relative to the mean deformation of the area. Using the height difference changes of the benchmark intervals, the probable fault lines were sought. The analysis shows that the bedrock at the Olkiluoto island is stable. Land uplift differences within the island are small. There seems to be no systematic deformation between the island and the mainland although more repeated measurements and longer time span is needed in order to get a reliable result. The most significant subsidence area of the island is over the ONKALO. Other one is GPS13, in the west-south of the island. In the Olkiluoto-Lapijoki line there are two subsidence areas: one is the eastside of the Olkiluoto strait, and the other is Lapijoki area. In the middle of the line is located 03205, which belongs to a local subsidence area. The rising area includes the island outside the ONKALO, and the benchmarks 03206 and 03204 in the Olkiluoto-lapijoki line. Some single elevation differences may occur on the island, but during the observation period, the individual benchmarks differ mostly less than one millimetre from the mean deformation of the research area. Interesting deformations include the movements of GPS6 and GPS9 from 2003 to 2005, and GPS13 from 2007 to 2009. GPS station GPS4 has the largest difference relative to 2003, but this deformation has happened gradually. The benchmark no. 06220 over ONKALO uplifted from 2006 to 2007. This movement continued in 2009 but in 2010 and 2011 the benchmark was at a lower level than in 2009. Kinematic deformation rate is slightly positive for this benchmark. In the loop VLJ, deformation is connected to control marks of GPS9. The Lapijoki-Olkiluoto line has been measured in 2003, 2007 and 2011. These measurements show that the linear movement between Lapijoki and Olkiluoto island is small. There are some unstable intervals inside the line. In comparison with 2003 observation in 2007 a remarkable movement was found in a benchmark interval 03208-03211 over the Olkiluoto strait. Later the movement over the Olkiluoto strait was found to be a little smaller and the measurement in 2011 gives the same result like 2007 measurement. The latest measurements show that the interval between benchmarks 04005 and 03211 had an elevation change between the 2010 and 2011 measurements.
