Strong earthquake jolts eastern Japan
A strong quake with a preliminary magnitude of 5.5 jolted eastern Japan today morning,but without reports of injury or even damage and no tsunami warning was issued.
The focus of the tremor was 20 km 12 miles below the surface of the earth,in Yamanashi prefecture, west of Tokyo, the Japan Meteorological Agency said.The quake,at 7:43 a.m., was felt in the capital as well.
Japan is considered to be one of the most seismically active areas in the world; about 20% of the world's earthquakes of magnitude 6 or greater.On March 11, 2011, the northeast coast was struck by a magnitude 9 earthquake, the strongest quake in Japan on record,and a massive tsunami,which triggered the world's worst nuclear crisis in 25 years since Chernobyl. The catastrophe left about 23,000 dead and missing.
