According to the Japan Meteorological Agency, the tremor occurred at around 4:52 p.m. off the Sanriku Pacific coastal area of northeastern Japan, with upper 5 seismic intensity observed in the town of Hashikami, Aomori Prefecture. The quake had an estimated magnitude of 7.7 and occurred at a depth of about 19 kilometers. Its moment magnitude was calculated at 7.4. Tsunami warnings were issued for Iwate Prefecture, the Pacific coast of Aomori Prefecture and the central area of the Pacific coast of Hokkaido, northernmost Japan.

Following Monday’s temblor, the agency issued an advisory on a possible subsequent quake off the Hokkaido and Sanriku regions. The weeklong advisory calls on people in a total of 182 cities, towns and villages in seven prefectures to take precautions until 5 p.m. on April 27.

Speaking to reporters at the prime minister’s office in Tokyo, Prime Minister Sanae Takaichi urged residents in areas where tsunami warnings and advisories, covering different expected wave heights, have been issued to evacuate to higher, safer areas. The government has set up a liaison office at the crisis management center of the prime minister’s office. Takaichi said the office will gather information about damage and provide information to the public. According to East Japan Railway Co., or JR East, services were temporarily suspended in both directions of the Tohoku Shinkansen bullet train line between Tokyo Station and Shin-Aomori Station. On Dec. 8 last year, a magnitude-7.5 tremor struck off the eastern coast of Aomori, registering upper 6 seismic intensity in Hachinohe. Tsunamis were observed along the coasts of Hokkaido and northeastern Japanese prefectures, and an advisory on possible subsequent quakes off the coasts of Hokkaido and Sanriku was issued for the first time. An earthquake occurred in the same area four days later, and tsunamis were observed in Hokkaido and Aomori. Japan’s Nuclear Regulation Authority said that no abnormalities from the latest quake have been detected at Tohoku Electric Power Co.’s Higashidori and Onagawa nuclear power plants in the prefectures of Aomori and Miyagi, respectively, and Japan Nuclear Fuel Ltd.’s spent nuclear fuel reprocessing plant in Aomori.
