How do we know if your place is located in the fault line?
The PHIVOLCS FaultFinder 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.
How do you identify a fault line?
To correctly identify a fault, you must first figure out which block is the footwall and which is the hanging wall. Then you determine the relative motion between the hanging wall and footwall. Every fault tilted from the vertical has a hanging wall and footwall.
Why is the Philippines host to 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.
Does Zambales have active faults?

Why is it important to know the location of faults?
To understand the risk that different areas of the U.S. face for earthquake hazards, we need to know where faults are and how they behave. We know a fault exists only if it has produced an earthquake or it has left a recognizable mark on the earth’s surface.
What is the difference between active and inactive faults?
Active faults are structure along which we expect displacement to occur. Inactive faults are structures that we can identify, but which do no have earthquakes.
What is the fault where the big one is expected to happen?
West Valley Fault
Who will be affected by the big one?
1,800 people will die. 1,600 fires will ignite and most of those will be large fires. 750 people will be trapped inside buildings with complete collapse. 270,000 people will be immediately displaced from their homes.
How likely is it that the Philippines could be hit by a tsunami?
The Philippines is vulnerable to tsunami due to the presence of offshore faults and trenches such as Manila Trench, Negros Trench, Sulu Trench, Cotabato Trench, Philippine Trench, and East Luzon Trough. Tsunamis in the Philippines are rare but could be devastating.
