Japan hit by 8.9 earthquake and tsunami MAR 11 2011
The quake is one of the most powerful ever to hit Japan.
The United States Geological Survey said the earthquake had a magnitude of 8.9, and occurred at about 230 miles northeast of Tokyo and at a revised depth of about 17 miles. The Japanese Meteorological Agency said the quake had a magnitude of 8.8, which would make it among the biggest in a century.
The quake occurred at 2:46 p.m. Tokyo time and hit off Honshu, Japan's most populous island. The quake was so powerful that buildings in central Tokyo, designed to withstand major earthquakes, swayed.
