1 STYLE GUIDE
EERI Grammatical Constructions and Style Choices
1.1 References: use End Notes (under the “References” tab above), and create bibliographic references for each End Note following the format in the References _ Section of this Report Template.
1. Please make sure all hyperlinked text is in this font color (Dark Red).
1.2 American vs. British English
2. While we have team members from Britain and New Zealand, EERI is based in the U.S. Let us go with American English. For example, use “neighbor”, not “neighbour.” Exceptions can be made for joint reports with non-U.S. partners.
1.3 Commas
1. Place a comma at the end of introductory clauses even if they are short. Example: “In most cases, red paint will work better.”
2. Place a comma after introductory words. Example: “Similarly, the houses were acceptable.
3. Place a comma after conjunctive adverbs (however, moreover, etc.). Example: I went to the store; however, I did not buy Sanything.
4. Commas before conjunctions (and, but, for, nor, or, yet, so). Example: I have two girls, and they are great.
5. Commas in a series: Use the comma before the “and” (example): I like raspberry, blackberry, and strawberry ice cream.
1.4 Hyphens and dashes
1. Do not confuse usage of hyphens and various types of dashes.
a. The hyphen is the shortest length line and is used for relatively few situations such as compound words (shelter-in-place), phone numbers (510-555-1212), and internet URLs.
b. The en dash is the next longest length and will be rarely used in this document. c. The em dash is the next longest length and is used in more situations, such as amplifying or explaining a
point. Example: The influence of three impressionists—Monet, Sisley, and Degas—is obvious in her work. i. There are a variety of other situations where the em dash can be used, but the situations are
complicated.ii. In Word, to type an em dash, type two hyphens and the next letter, then space. It will
automatically combine the two hyphens to the right length for the em dash.d. See the Chicago Manual of Style for details on the hyphen, en dash, and em dash.
2. There is no space before and after either the hyphen or the dashes.
1.5 Other
1. Numerals: Spell out numbers through nine, then go to 10. a. Numbers starting a sentence is spelled out regardless. Use numbers for typical construction terms.
2. Quotes and punctuation: Period goes inside quotation marks, as do commas. 3. Do not use shorthand for words, like “recon” instead of “reconnaissance.” No contractions, either.4. Define all acronyms the first time they are used in a section. Example: Earthquake Engineering Research
Institute (EERI).

3 EXAMPLE CHAPTER (TO BE DELETED)
3.1 Event Description
On November 14, 2016 at 12:02am local time (November 13, 2016 New Zealand at 11:02:56 UTC), the moment magnitude M7.8 Kaikoura earthquake occurred along the east coast of the upper South Island. The earthquake initiated in the Waiau Plains in North Canterbury, and involved multiple fault segments (Figure 3) as the rupture generally propagated northward over 150km to Cape Campbell in Marlborough (Building Seismic Safety Council (BSSC), 2009).1
The Marlborough Fault Zone (MFZ) is one of the most active crustal regions of New Zealand with many mapped active faults. Several significant rupture displacements occurred on previously unmapped fault segments, most notably the Papatea Fault near the Clarence River mouth. The most notable seismological aspect of the earthquake was the number of these fault segments which ruptured co-seismically in the same event. While previous surface mapping of these faults suggested they could be considered as separate fault segments for the purpose of earthquake rupture forecasting, clearly they are connected together at depth (or at least close to connected), and this event highlights the increased emphasis required to explicitly consider such complex multi-segment ruptures for future earthquake hazard and risk assessments as well as tsunami detection.
Surface rupture along the causative faults resulted in significant localized damage to transportation infrastructure near the coast and also fault rupture-induced landslides. The strong earthquake-induced ground motions in the near-source region also resulted in substantial landslides along State Highway 1. Ground motions with horizontal accelerations exceeding 1.0g were observed at four locations (two in the Waiau area, and also in Kekerengu and Ward). The ground motion

recorded near the hypocentre in Waiau also exhibited 2.7g in the vertical direction, exhibiting the so-called 'slapdown effect' with asymmetric accelerations, very similar to that at Heathcote Valley in the 2010-2011 Canterbury earthquakes.
The ground motions from this earthquake were recorded at 224 GeoNet strong motion and broadband stations. Acceleration response spectra from four of these stations are shown in Figure 4. Significant efforts from several groups are currently making use of these observations to understand the overall ground motion intensity in the region. Figure 5 illustrates the inferred peak ground velocity (PGV) and Modified Mercalli intensities (MMI) based on broadband ground motion simulation (see: https://www.youtube.com/watch?v=P7t2u61daPg)2.
The general northward rupture propagation in this event resulted in forward directivity effects in the Wellington region, with the closest rupture plane approximately 50 km from the Wellington Central Business District (CBD). The characteristics of the ground motion in the Wellington region resulted in both geotechnical and structural related damage (described in subsequent sections). Figure 6 illustrates the observed ground motions in the urban Wellington region. The summary statistics for typical mid and low-rise structures are also identified as a percentage of the ULS design response spectrum. In addition, the empirically-predicted response spectrum in Wellington CBD for the Kaikoura earthquake is also shown, which highlights the higher ground motion amplitudes in the 1-2 second period range. Figure 6, for context, also illustrates the empirically-predicted demands for a hypothetical Wellington Fault earthquake, indicating the significantly higher spectral demands expected across all period ranges for such an event.
Amplified spectral accelerations between periods of 1- 2 seconds were most significant in the soil deposits in the Wellington Basin and the Hutt Valley. As the soil depths increased, this amplification also increased, resulting in spectral accelerations that exceeded the design spectra in the 1-2 second period range in the deepest deposits along the edge of the Wellington waterfront. The significant duration of these records was approximately 25 seconds. The maps in Figure 7 present the spectral acceleration at different locations in Wellington region as a percentage of the ULS design spectra for 0.3 seconds and 1.5 seconds, indicating demands at or above ULS design spectra for many of the waterfront sites for T=1.5 seconds. Short period demands throughout the region were well below the design spectrum.

The section should assess further issues at the community and social level. For example: The earthquake affected all segments of society: the City Center has been cordoned off for 3 months; overall houses are maintained well and the earthquake shaking caused only limited structural damage to dwellings, but nonstructural damage was widespread; several telephone helplines were established to assist affected populations, included a line for those seeking information or financial support; recovery assistance centers and work and income service centers were opened in the region; official and unofficial social media presence was significant…

The paragraph should contain information regarding the performance of businesses and the general effects on the economy. For example: The businesses in the region affected were mainly SME. Some of them were forced to close but soon reopened within a week from the main shock, others were forced to relocate. The role of the insurance and the delays in the process of claims was fundamental.

The paragraph should contain information about lessons and main findings of the reconnaissance effort. For example: considered the spread collapse of URM buildings due to liquefaction, data from this event will help to understand the poor performance of some retrofitted URM buildings and develop better design approaches and standards; the earthquake emphasizes the need for cities to create a centralized and accessible database of structural drawings for use in emergency building evaluation.
