What does the PHILIPPINE FAULT ZONE comprise of?

Earthquake Effects

Usually occur along plate boundaries

The design and development of seismic recording systems

Ground failure effects

what theory suggests that if movement along a fault gets stuck, elastic strain energy builds up deforming rocks on either side of the fault.

Larger earthquakes after the main event, adjustment of the fault plane

It is the geographical point on the ground surface where an earthquake is estimated to be centered.

6

MAJOR EARTHQUAKE CLASS

Measures the strength of shaking produced by earthquake at a certain location.

What fault is defined with divergent plate boundaries?

Together with the epicenter, it gives the location where the rock ruptures at a fault that generates the main earthquake

It is the vibration of the earth produced by the sudden, rapid release of energy.

The radiating seismic waves are recorded using a seismometer at an observation station located at a distance

when both P and S waves reach the surface what does it make?

The plane along which the rock or crustal material has fractured
