Continued vigilance urged after southern Tokachi earthquake

A magnitude 6.2 earthquake struck southern Tokachi, Hokkaido, with a maximum seismic intensity of 5 strong. The earthquake occurred directly beneath the Hidaka Mountains. While this event was outside the area of a predicted megaquake from a recent Hokkaido-Sanriku Oki aftershock earthquake advisory, authorities have ended the advisory period. However, they urge continued vigilance for earthquakes of intensity 5 strong for about a week. The article emphasizes the ongoing risk of megaquakes along the Kuril and Japan Trenches, as well as the possibility of direct-hit earthquakes from active faults, urging residents to maintain preparedness measures.
