A significant 7.5-magnitude earthquake struck northeastern Japan late on Monday, leading to the evacuation of approximately 90,000 residents and prompting tsunami warnings that were later downgraded to advisories. The Japan Meteorological Agency (JMA) reported that a tsunami, with potential heights reaching 3 meters (10 feet), could impact the northeastern coast after the quake hit offshore at 11:15 p.m. local time (1415 GMT).
Initial tsunami warnings were issued for Hokkaido, Aomori, and Iwate prefectures. Following the earthquake, tsunamis measuring between 20 to 70 cm (7 to 27 inches) were recorded at various ports. However, in the early hours of Tuesday, the JMA reassessed the situation and downgraded the warnings to advisories, indicating lower estimated wave heights and a reduced risk of flooding.
The quake’s epicenter was located 80 kilometers (50 miles) off the Aomori coast, at a depth of 54 kilometers. On Japan’s 1-7 intensity scale, the tremor registered as an “upper 6” in Hachinohe city, Aomori prefecture, indicating extreme shaking that could prevent individuals from standing and lead to substantial damage, including the potential collapse of heavy furniture and damage to wall tiles and windows.
As of 1700 GMT, updates from public broadcaster NHK suggested there were no reports of major structural damage or serious injuries. A hotel employee in Hachinohe mentioned that several individuals were hospitalized with injuries, though all were reported to be conscious. Prime Minister Sanae Takaichi confirmed early Tuesday that seven injuries had been reported.
In response to safety concerns, East Japan Railway suspended some services in the affected area, which had previously endured significant devastation during the massive 9.0-magnitude earthquake in March 2011. As the situation develops, the community remains vigilant, demonstrating resilience and preparedness in the face of such natural challenges.
