PHIVOLCS Maps of Marikina Fault Line Affected Areas

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:

Here is a rough map showing the general location of Marikina Fault Line in Metro Manila:

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

Information on Fault Lines and Earthquakes from PHIVOLCS Fault Finder Map

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 the PHIVOLCS Fault Finder map. The Fault Finder map shows the distribution of active faults and trenches in the Philippines as delineated by PHIVOLCS. The picture below shows the general location of fault lines and trenches. The Fault Finder map of PHIVOLCS is much clearer and interactive so I suggest that you should look at it.

To see the regional distribution of fault lines in the Philippines, I suggest that you also look at the Fault Finder map of PHIVOLCS.

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