Kyodo News:Japan raises accident severity level to 5 in nuclear crisis Japan raised the severity level of crisis-hit reactors at the Fukushima Daiichi nuclear power plant from 4 to 5 on an international scale of 7, the same level as the Three Mile Island accident in the United States in 1979, Japan's nuclear safety agency said Friday.

The 2011 Sendai earthquake and tsunami was an 8.9-magnitude earthquake that created tsunami waves of up to 10 metres (33 ft). Reportedly, the epicenter was located off the Oshika Peninsula, the east coast of Tohoku, Japan on Friday, March 11, 2011 at 05:46 UTC (2:46 p.m. local time) at a depth of 24.4 kilometres (15.2 mi). The earthquake occurred 130 kilometres (81 mi) east of Sendai, Honshu, Japan. Its epicenter was 373 kilometres (232 mi) from Tokyo, according to the United States Geological Survey (USGS). A 7.1 magnitude aftershock was reported 40 minutes following the initial quake. At least twenty aftershocks of magnitude 5.5 or greater have occurred since the initial quake. Initially reported as 7.9 by the USGC, the magnitude was quickly restated as 8.8 and then 8.9. Wikipedia:2011 Sendai earthquake and tsunami
