The Philippines sits on the Pacific "Ring of Fire"

[Michael Grove]

 ... where tectonic plates collide deep below the Earth's surface.

 The Pacific Ring of Fire, as illustrated above is a horseshoe pattern of

 plate tectonic boundaries. The most violent catastrophes occur at

 convergent boundaries along the ring. When plates collide together,

 chains of volcanoes. are created. Almost all plate tectonics along the

 Ring of Fire collide and sink into the ocean floor as convergent plates.

 In fact, about 90% of the world’s earthquakes occur at these zones of

 subduction along the Pacific Ring of Fire.
