Understanding the earthquake in Japan

From today's News & Analysis on the AAAS Science web site:
"The 11 March Tohoku earthquake ranks among the five strongest temblors recorded by modern instrumentation. The U.S. Geological Survey and the Japan Meteorological Agency now peg the magnitude at 9.0. The quake ruptured more than 400 kilometers of crust along the Japan Trench subduction zone, where a tectonic plate is diving beneath the northeast coast of Honshu Island."
