PHIVOLCS is calling all owners of buildings and structures located on or near the Marikina Fault, which is now officially named as West Valley Fault, to be prepared as an earthquake may strike along Marikina Fault at any time. According to PHIVOLCS, the latest activity of Marikina Fault occurred at around 200 years ago and the accumulated stress will cause a major tectonic activity.


Yesterday, March 21, there is an earthquake that occurred off Lubang Island. It seems like that there is a rise of occurrence of felt earthquakes around the Philippines. Thus, it is no wonder that PHIVOLCS is anticipating movement of the Marikina Fault.

Due to this, many people are afraid of a major earthquake along Marikina Fault. Thankfully, PHIVOLCS drew maps of Marikina Fault, which shows where the fault lines are. Based on a PHIVOLCS document (Pdf file), Marikina Fault passes through Laguna, Muntinlupa City, Quezon City, Montalban (Rodriguez) Marikina City, San Mateo, Pasig City and Taguig City. Here is the diagram as shown on the document issued by PHIVOLCS:

Visit PHIVOLCS website to see the maps of areas affected by Marikina Fault. PHIVOLCS has 15 large scale maps, which is helpful in seeing if your home is near the Marikina Fault or not.

Map is obtained from the document, The Marikina Valley Fault System: Active Faulting in Eastern Metro Manila (Pdf file), as posted on PHIVOLCS website.

    @Nortehanon:

    Me too. Meron akong kakilala na affected ng Marikina Fault Line. Haist...yung mga local governments kasi, hinayaan na mag-develop ng mga subdivision sa mga dinadaanan ng Marikina Fault. :-(

    Nasa gilid kasi tayo ng Pacific Rim kaya maraming fault lines yng tectonic plates ng Pilipinas.

    Information regarding earthquakes and fault lines are important pero hindi ka dapat mag-alala ng todo. Be prepared na lang.

    I hope I heard the news right, that Quezon City government is asking residents residing near fault line to sign a waiver that they are warn of danger. It is up to the resident to leave or not.

    It is a lot of craps, why not check who approved those papers to have those subdivisions built. Arrest all those government officials and developers and let them rot in jail...NO BAILs

    I saw that news on TV one time Anonymous.

    I think gusto lang ng mga opisyal ng Quezon City Gov't na maghugas kamay kung may mangyaring lindol.

    Iwas pusoy lang sila.

    this has been affecting me much as i worry for the lives of my beloved esp my child. i live just less than a km from the faultline here in marikina. worse is Marikina is prone to liquefaction. sana naman may ginagawang drills sa bawat community. not only in school and work.much as i wanted not to get affected, i cant help it.going to malls and somewhere else has lessened, i am sad that my worries worsened everyday.

    Please don't scare yourself too much. What you should do is to prepare. If you have enough money then try looking for a new home away from the fault line.

    Is Glenrose East in Tikling Taytay Rizal is affected by this fault line?

    Thanks.

    Taytay is not included in the map provided by PHIVOLCS. It is highly probable that Taytay is not affected by Marikina Fault Line.

    it's a government fault line...hinayaan lang nila magdevelop ng mga human habitation knowing na hazardous area un..they risk human life for the sake of profits.

    Mga Sir, how about Vista Real Subdivision? Malapit po ba yun sa fault line? May bin ibalik kasi akong lupa doon. Salamat sa advise.

  23. Anonymous October 24, 2013 at 7:38 PM  

    are only those living on the fault line who need to prepare or move away from the fault line. what about those living in paranaque or pasay? how would they be affected? this fault is almost near mla bay.will it cause possible tsunami,thereby affecting those not on faultline but near the sea?

  24. Ishmael Fischer Ahab October 29, 2013 at 10:50 PM

    Saan babanda yung Vista Real Subdivision? Saan iyon malapit?

    Anonymous

    Dapat din pong maghanda yung mga malayo safault line kasi mararamdaman din ninyo yung bagsik ng lindol.

    Sa tingin ko ay walang tsunami na mangyayari kung yung Marikina Fault Line yung gagalaw. Nasa lupa po kasi yung fault line na iyon at wala sa dagat.

  25. Resilient November 22, 2013 at 7:08 PM  

    Wanted to ask again if Vista real subdivision is near the fault line????

    We are looking at a property to purchase in this subdivision and hope I can confirm whether this would be wise one of which whether it is earthquake prone or not.

    Thank you

    Sorry for the late reply. I checked the maps of Phivolcs and cross-referenced it with Google Maps. Based on my analysis, Vista Real is very near the Marikina Fault Line. I think that Delhi, Montreal, Detroit streets crosses the fault line.

    Is Ayala Westgrove near the fault line?

    I regret to say that PHIVOLCS large scale (and more accurate) maps of Marikina Fault Line ended in the Binan City area. Large scale map on this URL: http://www.phivolcs.dost.gov.ph/html/update_SOEPD/hazard_maps/active_faults/VFS/alvarez.pdf

    Hence, I had no choice but to use the small-scale, which is less accurate. Small scale PHIVOLCS map on this URL: http://www.phivolcs.dost.gov.ph/images/active.faults/region%20iv-a.pdf

    I overlaid PHIVOLCS map with Google Map. The result is that the fault line (red line) passes through Ayala Westgrove Heights and Adventist University of the Philippines. See the combined maps that I made by clicking this link: Ayala Westgrove and Adventist University of the Philippines fault line.
