A powerful 6.9-magnitude earthquake struck off the coast of northern Japan on June 24, 2026, according to the Japan Meteorological Agency. The quake, which occurred at a depth of approximately 40 kilometers, prompted tsunami advisories for coastal areas but no immediate reports of major damage or casualties.
Details of the Earthquake
The earthquake struck at 7:23 p.m. EDT (8:23 a.m. JST on June 25) off the coast of Hokkaido and northern Honshu. The Japan Meteorological Agency issued a tsunami advisory for waves up to 1 meter along the coastlines of Hokkaido and the Tohoku region. Residents were urged to evacuate to higher ground and stay away from the coast until the advisory was lifted.
According to the U.S. Geological Survey, the earthquake had a magnitude of 6.9 and was centered about 150 kilometers east of Kushiro, Hokkaido. The quake was felt strongly in cities such as Sapporo and Sendai, where buildings swayed for several seconds.
Impact and Response
No significant damage or injuries have been reported so far, and the tsunami advisory was later downgraded. Japanese authorities deployed emergency teams to assess the situation and monitor for aftershocks. The earthquake did not trigger any major industrial incidents, and nuclear power plants in the region reported no abnormalities.
This earthquake comes as Japan remains on high alert for seismic activity, given its location along the Pacific Ring of Fire. The country experiences about 20% of the world's most powerful earthquakes.
