A magnitude 7.4 earthquake with a depth of 57 to 60 kilometers hit northeast Japan on March 16, at 23:36 local time. More than 2.2 million homes in 14 prefectures, including the Tokyo area, temporarily lost electricity. According to the local electric provider, most neighborhoods had power restored by mid-morning. A bullet train was also reported to have been derailed north of Fukushima City, but it was not traveling fast and no passengers were injured. However, 78 passengers, including staff, were trapped on board for four hours before escaping. Authorities in Fukushima, Miyagi, and Yamagata prefectures have issued warnings about possible aftershocks. Japan’s Prime Minister, Fumio Kishida, told reporters that the government was still investigating the degree of any damage and that emergency services had received a flood of calls. The Meteorological Agency issued a public advisory on Thursday, and more earthquake activity is expected in the following days. The agency’s representative, Masaki Nakamura, also warned residents about the possibility of mudslides.
