The calamity that occurred in Japan last Friday sparked the attention about the safety of the Philippines about earthquakes and tsunamis. PHIVOLCS and the government assured that the new high-rise buildings around Metro Manila are sound enough to withstand earthquakes. However, many people are still concerned, especially because of the many fault lines around our country.

For those who are looking for a map issued by PHIVOLCS that shows the major fault lines, I suggest that you visit this PHIVOLCS page (PDF document). The map shows the distribution of active faults and trenches in the Philippines as delineated by PHIVOLCS. The picture below shows the preview of that map from PHIVOLCS. The PDF file from PHIVOLCS is much clearer so I suggest that you should look at it.

To see the regional distribution of fault lines in the Philippines, I suggest that you visit this PHIVOLCS page.

Be prepared for earthquakes and the best preparation is to gain knowledge.

    Hi Anon.

    Baka yung mapa ng buong Pilipinas ang nakita mo? For better maps, I suggest that you visit this page ng Phivolcs: http://www.phivolcs.dost.gov.ph/index.php?option=com_content&view=article&id=78&Itemid=130

    Large scale ang maps diyan at naka-ayos per region.

    Hello Anonymous

    PHIVOLCS doesn't have the map you need. The only map available is this: http://www.phivolcs.dost.gov.ph/images/active.faults/region%20vi%20and%20vii.pdf

    HI! DO YOU HAVE DOCUMENTS INDICATING THE TYPE OF FAULTING MECHANISM FOR EACH ACTIVE FAULT? THIS DATA ARE REQUIRED TO SEARCH FOR ACCELEROGARAM RECORDS FROM THE "PEER STONG MOTION DATABASE". http://peer.berkeley.edu/smcat/search.html
    WE DO THIS TO PERFORM TIME-HISTORY ANALYSIS OF STRUCTURES.

    I don't have those documents. I suggest that you contact PHIVOLCS so they can help you with your concern.

    Ano po yung ibig ninyong sabihin sa Feb 22 earthquake? May nag-predict po ba na may lindol nangyari noong Feb 22?

    Tungkol naman po sa tanong ninyo, malungkot pong sabihin pero totoo po yung nasa balita. Maraming mga lumang gusali ang tiyak na bibigay kapag lumindol sa Marikina Fault Line.

    Kung nakatira kayo sa Metro Manila ay tingnan po ninyo kung yung bahay ninyo ay malapit sa isang fault line. Tapos tingnan ninyo kung matibay pagkagawa ng bahay ninyo.
