Is Palawan safe from earthquake?

According to PHIVOLCS, it has no active faults lines, no active volcanoes, and no deep trenches but it is still vulnerable to earthquake hazards particularly tsunamis. According to study, the Northern Palawan’s foundation is composed of continental terrain which is originally part of the Eurasian plate…..

Why do the Philippines have too many active faults?

The Philippine Mobile Belt is compressed on the west by the Eurasian Plate and two arms of the Sunda Plate, and on the east by the Philippine Sea Plate. These tectonic plates have compressed and lifted parts of the Philippines causing extensive faulting, primarily on a north–south axis.

What are the major faults in the Philippines?

The Philippine Fault System is a primary inter-related system of geological faults throughout the Philippine Archipelago, [1] primarily caused by tectonic forces compressing the Philippines into what geophysicists call the Philippine Mobile Belt. [2] Some notable Philippine faults include the Guinayangan, Masbate, and Leyte faults.

[2]

How does the PHIVOLCS faultfinder work?

The PHIVOLCS FaultFinder is an application capable to do proximity searches to active faults. It may be used to determine the location of active faults in an area and to measure the shortest distance between an active fault and a user’s current location, which is determined by the gadget’s tracking device.
