Shake, Rattle, and Rolling Waves
The Philippine Fault Zone is a generally sinistral fault that runs practically through the entire length of the archipelago, and it is the immediate effect of the collision on the Philippines. It is known to have caused several major earthquakes with varying degrees of destruction and damage throughout the country.
Do you think this fault or segments of this fault can trigger tsunamis, particularly in relation to the “Big One?” Explain your answer.

Answer:
Yes, the Philippine Fault Zone and its segments have the potential to trigger tsunamis, particularly in relation to the "Big One" earthquake scenario.
Tsunamis are typically caused by large earthquakes that occur in the ocean floor or along a subduction zone. In the case of the Philippine Fault Zone, it is a major fault system that is capable of producing large and destructive earthquakes. A particularly strong earthquake along this fault zone could generate a tsunami that could affect coastal areas of the Philippines.
The "Big One" earthquake scenario refers to a hypothetical earthquake that is expected to occur along the West Valley Fault, a major fault system that runs through Metro Manila and nearby provinces. However, the Philippine Fault Zone also intersects with the West Valley Fault, and a major earthquake along this fault zone could also trigger a tsunami.
It is important to note that the probability of a tsunami occurring as a result of an earthquake along the Philippine Fault Zone or the West Valley Fault is still uncertain and difficult to predict. However, the Philippine Institute of Volcanology and Seismology (PHIVOLCS) has been conducting studies and assessments to better understand the seismic hazards in the Philippines and to develop strategies for disaster risk reduction and management.
