In the previous post, I talked about PHIVOLCS list of fault lines and maps. Now, related to earthquake is the tsunami. According to PHIVOLCS, tsunami is a series of waves generated by a shallow seated earthquake on the seabed.

Just like what happened to Japan this month, tsunami occurred right after the strong earthquake. According to some reports, the tsunami generated by the earthquake is as fast as a jet plane so that few managed to escape the tsunami.

To help the people in coastal areas, PHIVOLCS collected data and created a map to show tsunami prone-areas in the Philippines. Shown below is a screen grab of Tsunami Prone Area Map from PHIVOLCS.

To view the copy of PHIVOLCS' map, I suggest that you visit this PHIVOLCS web page.

PHIVOLCS made this map so as to help the Filipino people know if they are threatened by tsunami and so that we can prepare accordingly.

For more information about earthquakes, visit my posts: PHIVOLCS List of Fault Lines and Maps and PHIVOLCS Tips on what to do before, during and after the occurrence of earthquake, and PHIVOLCS Map of areas affected by Marikina Fault.

    Lahat po ng coastal areas ay prone sa tsunami since naliligiran ang buong Pilipinas ng trenches at fault lines.
