The Philippine islands are susceptible to tsunamis when a large enough earthquake occurs within a certain distance and depth of its coast. When large earthquakes occur off its coast, a tsunami warning is typically issued for the region nearby, causing people living on the coast to move to higher ground.
In 2012, a 7.6 magnitude earthquake that occurred 91 miles off the east coast of the Philippines led the Pacific Tsunami Warning Center to issue a tsunami warning. The initial warning was issued for a wide geographical region, including Japan, Indonesia, Taiwan, Hawaii and the Philippines. While the warning was later scaled back, people in the Philippines were warned of a potential tsunami hitting the country's coastal regions.
