2002 Mindanao earthquake : ウィキペディア英語版 | 2002 Mindanao earthquake
The 2002 Mindanao earthquake struck the Philippines on March 5. The sixth most powerful earthquake of the year, it registered a magnitude of 7.5 and was a megathrust earthquake. It originated near the Cotabato Trench, a zone of deformation situated between the Philippine Sea Plate and the Sunda Plate. The entire country is characterized by a high level of volcanic and seismic activity. The earthquake was responsible for 15 deaths and roughly 100 injuries. Up to 800 buildings were damaged as a result, many from a flood generated by landslides and falling debris. A tsunami followed the earthquake. == Geology == The epicenter of the earthquake was located near the Cotobato Trench; the magnitude of this megathrust earthquake was 7.5, the sixth strongest of the year. It occurred in a zone of geologic deformation along the Sunda and Philippine Sea Plates, which converge at a rate of each year. The Philippines sits on several microplates between two convergent plates, the Philippine Plate and the Eurasian Plate. Tectonic activity in the country includes both earthquakes and volcanic eruptions. Because of subduction of the Eurasian Plate to the west, volcanic activity occurs along the Manila Trench and the Sulu Trench, often of powerful caliber. 13 percent of recorded eruptions in the Philippines have been deadly, as the country is responsible for the world's most deaths in volcanic eruptions. Seismicity as well has been powerful: in the last 50 years, more than half of the country's major earthquakes have reached magnitude 7.0 or greater. The earliest known major shock was in 1976, killing some 8,000 people. The Mindanao event was the fourth of seven major events since 1975.
