Why did the earthquake happen here?
Three crustal plates meet near to the coast of Japan. Close to Kobe, the denser oceanic Philippines Plate is being subducted beneath the lighter continental Eurasian Plate at a rate of about 10 centimetres per year. The Japanese island arc has been formed from the molten magma released by the melting Philippines Plate. Earthquakes are very common here and happen because of the friction resulting from the two plates colliding along this destructive margin. [In 1923, the Great Kanto Earthquake killed 140,000 people in this area.] The great destruction which resulted from the 1995 Kobe Earthquake was due to the shallow depth of the focus which was only about 16 kms. below the surface and the fact that the epicentre occurred close to a very heavily populated area. Seismic shockwaves travelled from Awaji Island (the epicentre) along the Nojima Fault to the cities of Kobe and Osaka.
