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.

    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.
