Around 11:07 pm on the 13th, there was an earthquake with a seismic intensity of more than 6 in Nakadori and Hamadori in Fukushima prefecture, in the southern part of Miyagi prefecture. More than 30 people were injured, according to fire departments in both prefectures. Information such as fires and rockslides in apartment buildings and disconnection of electrical cables have been reported one after another, and large-scale power outages have occurred mainly in the Tohoku and Kanto regions. According to the Japan Meteorological Agency, it appears to be a replica of the Great East Japan Earthquake 10 years ago. During the next week, we must be careful with earthquakes with a seismic intensity of 6 or more.
According to the Japan Meteorological Agency, the epicenter is off the coast of Fukushima prefecture, and the depth of the epicenter is about 55 km. The magnitude of the earthquake is estimated to be 7.3 degrees (M). After that, earthquakes continued with a seismic intensity of 3. This is the first earthquake with a maximum seismic intensity of 6 or more that originated off the coast of Tohoku in 10 years since April 7, 2011. There may be some fluctuations in sea level along the coast, but there is no concern about a tsunami.
The government has established an official residence countermeasures office in the crisis management center of the prime minister’s official residence and is gathering information with Prime Minister Yoshihide Suga and Hachiro Okonogi, the minister in charge of disaster prevention. The National Police Agency has established a disaster security headquarters. Defense Minister Nobuo Kishi ordered the Self-Defense Forces to take immediate action to understand the damage situation and respond to disasters.
Miyagi and Fukushima prefectures have also established a disaster response headquarters and are rushing to check on the situation.
Under the East Nippon Expressway, the Tohoku Expressway and Joban Expressway have been closed. On the Joban Highway, road surface uplifts and landslides occurred.
According to JR East, Tohoku, Joetsu, Hokuriku and Tokaido Shinkansen will be temporarily suspended due to power outages in some sections. According to the power companies, there were also power outages in at least 900,000 houses in a wide area from Tohoku to Kanto and Tokai.
According to TEPCO, no data changes have been reported at the monitoring posts that monitor radiation at the Fukushima Daiichi nuclear power plant. According to each electric power company, there are no notable anomalies in the equipment at the Onagawa Nuclear Power Plant in Miyagi Prefecture, and there are no changes in the values of the radiation monitoring equipment. There are no anomalies at the Higashidori Nuclear Power Plant (Higashidori Village, Aomori Prefecture). There were no anomalies at the Tokai No. 2 nuclear power plant in Ibaraki prefecture and the Kashiwazaki-Kariwa nuclear power plant in Niigata prefecture.
