Magnitude 9.1 Japan (Historical Earthquake)

Ten years ago today a magnitude 9.1 earthquake occurred in Japan. The earthquake struck off the northeastern coast of Honshu, Japan’s main island, and initiated a series of large tsunami waves that devastated many coastal areas of the country, most notably in the Tōhoku region (northeastern Honshu). The tsunami also instigated a major nuclear accident at a power station along the coast.
