Largest earthquake since 1900 hits Japan; not enough tsunami warning

摘要

On March 11, disaster struck Japan as a massive 8.9 magnitude earthquake generated a wall of water that surged over the east coast of the island nation, sweeping many to their deaths. Japan is situated along the world's most active earthquake belt, the Pacific Ring of Fire, where rigid plates in the Earth's crust collide along the rim of the Pacific Ocean. This earthquake originated 231 miles (373k) northeast of Tokyo and 80 miles (130km) east of Sendai, Honshu in the Pacific Ocean. The earthquake occurred at a depth of about 15.2 miles (24.4km).
