6.2 Magnitude Earthquake Shakes Hokkaido Days After Megaquake Alert

A magnitude 6.2 earthquake struck Hokkaido early Monday, just days after a powerful offshore tremor triggered a rare megaquake advisory in Japan.
According to the Japan Meteorological Agency, the quake hit at around 5:23 a.m. local time near the town of Sarabetsu at a depth of more than 80 kilometres. Despite being widely felt, authorities reported no casualties, significant damage, or tsunami risk.
The tremor follows a 7.7-magnitude offshore earthquake last week that prompted warnings of a potential «megaquake.» However, Monday’s event occurred outside the advisory zone, and officials said the heightened alert period will conclude as planned.
Experts noted the quake’s depth likely reduced its impact at the surface, though residents reported noticeable shaking across parts of northern Japan.
Authorities have warned of possible aftershocks and secondary hazards such as landslides, urging residents to remain cautious in the coming days.
Japan, located along the Pacific Ring of Fire, experiences frequent seismic activity but relies on strict building standards and advanced early warning systems to minimise damage and casualties.
