What are the most active faults in the Philippines?

The central Philippine Fault Zone consisting of the Guinayangan, Masbate, and Central Leyte faults are the most seismically active regions transecting the islands of Bondoc to Leyte.

What are the five active faults found in our country?

What is the big one in the Philippines?

The “Big One” is a worst-case scenario of a 7.2-magnitude earthquake from the West Valley Fault, a 100-kilometer fault that runs through six cities in Metro Manila and nearby provinces. A tsunami is also foreseen in the scenario set by the Philippine Institute of Volcanology and Seismology (PHIVOLCS).

Is it safe to live near a fault line?

Living near fault lines is inherently dangerous but difficult to avoid. Evidence suggests that humans congregating around tectonic faults (areas where the plates that make up the lithosphere above the Earth’s mantle travel and sometimes cause earthquakes) was no accident.

Where are active faults located?

Location. Active faults tend to occur in the vicinity of tectonic plate boundaries, and active fault research has focused on these regions. Active faults tend to occur less within the area of any given plate. The fact that intraplate regions may also present seismic hazards has only recently been recognized.

What causes faults to move?

Tensional stress is when rock slabs are pulled apart from each other, causing normal faults. With normal faults, the hanging wall slips downward relative to the footwall. … These rocks move like your hands do when you rub them together to warm up. The movement along faults is what causes earthquakes.
