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:

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

    hi...ask ko lang po about doon sa interview sa tv patrol news tungkol sa possible earthquake this feb.22,2013 i don't remember po kc the exact date nong news pero naglagay kc ako ng reminder alarm sa calendar ng phone ko about sa napanood ko nga sa news na magready kc nga possible na mag-ka earthquake sa manila and maraming buildings ang masisira kc mahina ang mga pagkakagawa...totoo po ba un??? knina p po kc ako naghahanap nong news na napanood ko b4 na news di ko na makita.. help me pls kung tama nga po ba ako?

  19. Ishmael Fischer Ahab February 21, 2013 at 8:31 PM  


    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.

    I wanted to know the exact location of a fault line here in Talisay City, Cebu as I lived here in Talisay and there's a 7.2 quake here yeterday. thanks.

    Hi! Just wanna ask, meron po bang fault line na near sa Baguio?

  27. Ishmael Fischer Ahab June 2, 2014 at 11:54 AM  


    Base sa mapa ng PHIVOLCS ay walang fault line sa mismong Baguio City. Kaso may fault lines sa paligid ng Baguio.

    Please check the PHIVOLCS map at this URL:

    Hello, Ishmael. Thank you for your post.

    And I want to point out how patiently you answered each comment reminding them of your suggestion to open the PDF and visit the PHIVOLCS site for more information. It's funny they'd leave these comments when they haven't read your post. Halatang hindi nagnabasa.

    Hi, I want to see or know the specific areas of active west valley fault of Pasong Putik Proper Quezon City. Please.

    If you want the specific area, I suggest that you refer to the map in Nababaha.Com which may be seen at this URL:

    Hi I'm Poch

    Pwede po ba namin makita ang specific na lugar o barangay kung saan andoon ang active fault line sa mapa ng san fernando city, la union? Meron kasi kaming mga barangays kung saan ay may parte na parang lumulubog po.

    Salamat po.
