A 7.2 magnitude earthquake on the Richter scale shook the northern region of Japan early this Thursday, according to the country's Meteorological Agency, which has decided not to activate any tsunami alerts. So far, no casualties or material damage have been reported.
The agency had initially indicated that the earthquake was of magnitude 6.9, although it revised the figure upwards shortly thereafter. It also detailed that the epicenter was located off the coast of Iwate prefecture, with a hypocenter at a depth of approximately 44 kilometers.
Authorities have indicated that the most affected locality is Hashikami, in Aomori prefecture, where the tremor was felt most strongly. Three other aftershocks have been recorded in the same area since the first earthquake.
"In areas affected by strong tremors, the risk of house collapses and landslides is high," the agency warned, urging the public to "pay close attention to seismic activity and predicted rainfall conditions." "Take precautions to ensure your safety by avoiding dangerous areas unless absolutely necessary," it stressed.
The agency added that the tremor "does not meet the criteria for issuing an alert about a possible subsequent earthquake off the coasts of Hokkaido and Sanriku," although it insisted that "in the areas of these prefectures that experienced strong tremors, the ground may have weakened and, therefore, the risk of landslides due to rain is considered higher than usual."
Japanese Prime Minister Sanae Takaichi stated that she has already ordered "a rapid assessment of the extent of the damage" and "close cooperation" with local authorities for rescue and aid efforts for those affected. She also specified that the Executive has set up "a crisis management office" and assembled "an emergency response team" to coordinate actions.
"Following my instructions, they are working diligently to assess the damage, carry out rescue and assistance efforts, and provide timely and accurate information to the public," she stated in a message disseminated on social media. "For those in areas affected by strong tremors, we ask you to remain alert to the possibility of similar earthquakes," she added.
