Tsunami warnings issued after a 7.5 magnitude earthquake in northern Japan
struck northern Japan A 7.5 magnitude
According to the Japan Meteorological Agency, the earthquake struck at 4:53 p.m. Japan time (07:53 GMT) in the Pacific Ocean off the coast of northern Iwate Prefecture. About 40 minutes after the quake, an 80-centimeter tsunami wave struck the port of Kuji in Iwate, amid fears of further waves. The agency initially estimated the earthquake's magnitude at 7.4 before revising it upwards to 7.5.
Aftermath of an earthquake in northern Japan and weather warnings
The Japan Meteorological Agency issued urgent advice to residents to immediately evacuate coastal areas and riverbanks, and head to higher ground and safe shelters. The agency warned that tsunami waves could strike repeatedly, emphasizing that people should not leave safe areas until the warning is completely lifted. In a subsequent development, the agency issued an exceptional warning indicating an increased risk of another devastating earthquake of magnitude 8 or higher, confirming that the probability of another major earthquake is relatively higher than usual for this time of year.
Japan and the Ring of Fire: A long history of confronting natural disasters
Japan is one of the world's most seismically active countries, situated at the intersection of four major tectonic plates along the western edge of the Pacific Ring of Fire. This unique geographic location makes the country vulnerable to approximately 20% of the world's major earthquakes annually. This recent event brings to mind the historic disaster of 2011, when a devastating magnitude 9 earthquake struck off the east coast, triggering a massive tsunami that resulted in significant loss of life and extensive damage to the Fukushima nuclear power plant. This explains the swift and decisive response of Japanese authorities to any new seismic activity.
Government response and expected impacts at the local and international levels
Locally, initial footage broadcast by Japan's public broadcaster NHK showed no immediate visible damage at ports in Iwate Prefecture. However, a Meteorological Agency official warned at a press conference that strong aftershocks, potentially more powerful than the initial quake, were possible in the coming days.
In response to the crisis, the Japanese government announced the formation of a special crisis management team to monitor developments and coordinate rescue and evacuation operations. Prime Minister Sanae Takaichi, in remarks to reporters, urged residents in threatened areas to strictly adhere to evacuation orders and move to higher ground, emphasizing that the government's top priority was ensuring the safety of lives and minimizing any material or human losses.
At the regional and international level, neighboring countries in East Asia and the Pacific are closely monitoring the situation, given the potential impact of the tsunami waves on maritime traffic and global supply chains, as Japanese ports are a vital artery for international trade.
