Vibrations (earthquakes) occur as the deformed rock “springs back” to its original shape (elastic rebound). Physical Causes The earthquake of Kobe at 546am on the 17th January 1995 was caused by the simple matter of the Philippine Plate being forced under the thicker and lighter continental plate the Eurasian. This has long been apparent from early catalogs of felt earthquakes and is even more readily discernible in modern seismicity maps, which show instrumentally determined epicentres. Tectonic earthquakes: The most common form of earthquakes, is caused by the movement of loose fragmented pieces of land on earth’s crust knowns as tectonic plates. Landslides, triggered by earthquake, often cause more destruction than the earthquake themselves. Dams: The build-up of pressure due to the storage of a large amount of water in the reservoirs behind large dams is considered to be a potential cause of earthquakes.
