What are the affected areas of Central Philippine Fault?

What type of fault is the central Philippine Fault?

Abstract. The central Philippine Fault Zone is found to be the locus of great earthquakes, a transition zone with slow slip and creep activity. This is based on the analysis and correlation of seismic historic data and detailed documentation of recent seismic events in the region.

What is the Philippine Fault Zone and where is it located?

The 1,200-km-long Philippine fault zone (PFZ) is a major tectonic feature that transects the whole Philippine archipelago from northwestern Luzon to southeastern Mindanao.

Where is a normal fault located?

Normal Faults: This is the most common type of fault. It forms when rock above an inclined fracture plane moves downward, sliding along the rock on the other side of the fracture. Normal faults are often found along divergent plate boundaries, such as under the ocean where new crust is forming.

What is the most active geologically active fault in the Philippines?

Marikina Valley Fault Line

according to PHIVOLCS, it is the most geologically active fault line the Philippines. it has not moved to produce high intensity earthquake for at last 500 years.

What are 4 types of faults?

There are four types of faulting — normal, reverse, strike-slip, and oblique. A normal fault is one in which the rocks above the fault plane, or hanging wall, move down relative to the rocks below the fault plane, or footwall.
