The earthquake occurred in the western Pacific Ocean, 130 km east of Sendai city, Honshu, Japan. The epicenter was 373 kilometers (232 miles) from Tokyo. Aftershocks with a magnitude of 7.1 on the moment magnitude scale occurred 40 minutes after the main tremor. More than 40 aftershocks of 5 or more moment magnitudes were recorded within hours of the main tremor. The United States Geological Survey initially reported the quake as 7.9, but later revised it to 8.8 and 8.9 Mw.
