More often than not, natural phenomena such as earthquake in the Philippines almost always caught us off guard. The 7.2-magnitude quake that recently hit Central Visayas is no exception.
With over 150 casualties and astonishing number of damaged historical churches, the earthquake that hit Visayan provinces on Tuesday is one of history’s strongest. In fact, Philippine Institute of Volcanology and Seismology (Phivolcs) Director Renato Solidum said that its impact is almost equivalent to “32 Hiroshima bombs.”
What causes earthquakes?
Earthquake is formed when plates underneath the Earth’s surface move in different directions. These plates often form a friction between each other in areas called faults. Once the impact of the collision becomes significant, it sends a signal on an outward direction commonly known as seismic waves.
Depending on the intensity, earthquakes may cause minor disruption or significant damage in properties. Here are history’s top 5 strongest earthquakes that caused major destruction in the Philippines:
