1. Volcano Information: Bulletin, Update, AdvisoryVolcano Bulletin – written report issued when there are unusual
volcanic activities that may lead to an eruption- ash explosion- remarkable seismic activity- ground deformation
also issued when raising or lowering a volcanoalert status
describing an on-going eruption- concise interpretation of the volcanoobservations, which is the basis for publicwarning issued
Volcano Advisory – written report issued when the volcano exhibits an
increasing volcanic activity, or any other suddenchanges in activity, but that the observations arenot sufficient to warrant upgrading of the volcano’salert status.
If volcanic activity continues to increase,the advisory may be upgraded to a bulletin.
An advisory is also issued during typhoons orperiod of continuous heavy rainfall capable ofgenerating lahars. It advises people to avoid areasprone to lahar inundation.
1. Volcano Information: Bulletin, Update, Advisory
ALERT CRITERIA INTERPRETATION/
0(NORMAL)
All monitored parameters are withinbackground/ baseline levels. No eruption is foreseen.
1(ABNORMAL)
Slight increase in volcanic earthquakes,steam/gas activity, slight inflation.
The source of activity is shallow or near crater. Entryinto PDZ is forbidden.
2Elevated Level ofVolcanic Unrest
Elevated levels of any of the following: volcanicearthquakes, steam/gas activity, grounddeformation, other parameters..
Probable ascent and intrusion of magma which maylead to eruption within weeks or months. Entry into PDZis forbidden.
3High Level of
Volcanic Unrest
Relatively high and increasing unrest due tofurther intensified in volcanic earthquake, gas,ground deformation parameters
Magmatic processes underway and may lead toeruption within days to weeks. Evacuation of hazardzones.
4HazardousEruptionImminent
Intense unrest characterized by earthquakeswarms and tremors, many perceptible, highgas output, intense ground deformation.Activity may involve lava extrusion and domegrowth.
Low-level eruption in progress and may lead tohazardous highly explosive eruption. Hazard zones maybe extended for a few kilometers or more.
5Life-Threatening
ERUPTION
Highly explosive eruption in progress withbillowing tall ash-laden eruption columns, inexcess of tens of kilometers, widespreaddispersal of volcanic hazards..
Hazardous eruption in progress. Flowing or fallingmaterials encroach into settlements. Additional dangerareas may be recommended as eruption progresses.

Earthquake Information – written report of significant - usually perceptible or felt
earthquake events
This contains information about the earthquakeoccurrence
This is immediately relayed to concerned authoritiesand local government units, disaster agencies andthe media

Tsunami Information Threat to the Philippines Recommended Action forAffected Places
Advisory
NO TSUNAMI THREAT
A large earthquake isgenerated but either(1) There is no tsunami
generated by this event or(2) A tsunami was generated but
will not reach the Philippine
No evacuation needed.The information is issuedfor information purposesonly.
Advisory
SEA LEVEL CHANGEMONITORING
PHIVOLCS will monitor sealevel changes and provideupdates.
No evacuation order is ineffect.Public is advised to wait
and listen for updates.
Advisory
MINOR SEA LEVELDISTURBANCE
Minor sea leveldisturbance is expected insome coastal areas
People are advised to stayaway from the beach andnot to go to the coast.
WarningTSUNAMI WARNING
Destructive tsunami isgenerated with lifethreatening wave heights.
Immediate evacuations ofcoastal communities thatmay be affected arestrongly advised.

4.2 Volcano Information description of the volcano
- physical features- location and accessibility- classification- geological features- studies or field investigations undertaken atthe volcano- monitoring methods and techniques- historical eruptions (usually extracted from
the volcano catalogue).
4. Catalogue
PHIVOLCS Certification states whether a volcano orearthquake hazard is present or absent inan area.
It is required by certain government agencies as asupporting document in relation to a customer’sapplication for loan, permit for land development andother government transaction.
PHIVOLCS Certification by itself is NOT an approval,endorsement or authorization for further governmentprocedure.

Ground Shaking Hazard Map - probability of occurrenceof ground shaking over a given time period of seismichazard and related uncertainties
Seismicity Map - shows the plots of epicenters ofearthquakes, indicating magnitude anddepth, that occurred in a particular area and period
6. Hazard MapsPHIVOLCS produces maps showing areas prone toearthquake or volcanic hazards. These are madeavailable to users either as printed output or digital data.
Earthquake
other earthquake hazards Active Faults and Trenches Map – show the distribution of
earthquake generators in the Philippines
Earthquake-induced Landslide Hazard Map – indicativeregional map showing areas at high-, moderate-, or low-risk to slope failure
Liquefaction Hazard Map - indicative regional mapshowing areas prone to ground failure
Tsunami Hazard Map – show the computed worst-casetsunami wave height and inundation coming from thelargest credible earthquake from an off-shore earthquakegenerator
6. Hazard Maps
VolcanoLahar Hazard Map – shows the areas prone to rain-induced flow of volcanic deposits on slopes of activevolcanoes;
6. Hazard Maps
available for selectedactive and potentiallyactive volcanoes ofthe Philippines –Pinatubo, Mayon,Bulusan, Hibok-hibok, Kanlaon, Iriga,Parker, Cabalian,Banahaw.
Volcano Lava Flow Hazard Map – shows the areas prone to
stream-like flows of hot incandescent molten materialsfrom an erupting volcano; available for selected activevolcanoes of the Philippines.
Pyroclastic Flow Hazard Map - shows the areas proneto turbulent flows of hot gases, ash and rocks from anerupting volcano; available for selected active volcanoesof the Philippines.
6. Hazard Maps
Group tours (e.g schools, GOs, NGOs), a venue forlecture, film showing, and guided exhibit viewing.
Smaller groups of students (15 or less) are also allowed toview the Data Receiving Center (DRC). Technicalpersonnel are tapped to give them lectures.
Film showing may be any of the following: volcanoes andvolcanic hazards, earthquake or tsunami. Technicalpersonnel are available to answer questions after videoviewing or during exhibit viewing.
