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.

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.

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.
