Earthquake Rocks Japan

March 10, 2011 | Top News

The east coast of Honshu, the largest and main island of Japan, was struck by a 7.2-magnitude earthquake on Wednesday.   More than 20 aftershocks followed with four tremors felt today that measured 6 or greater in magnitude.  Although the quakes were strong and caused buildings to shake in the capital city of Tokyo, no damage or injuries have been reported.  Authorities said that the tremor was at a shallow depth of 10–20 kilometers below the Pacific seafloor.

Japan is composed of islands that lie on a very unstable part of the earth which is constanly shifting. It is  one of the countries that sits on the Pacific Ring of Fire and has always been hit by 20% of the world’s most powerful earthquakes.  For the next 30 years, Japan may experience bigger tremors and the country has been well-prepared for this kind of events.
