Moderate yet deep earthquake of magnitude 5.4 just reported 89 km northwest of Minatomachi, Japan

An earthquake of magnitude 5.4 occurred in the morning on Monday, March 10th, 2025, at 9:51 am local time near Minatomachi, Yoichi-gun, Hokkaido, Japan, as reported by Japan's National Research Institute for Earth Science and Disaster Resilience (NIED).
According to preliminary data, the quake was located at an intermediate to considerable depth of 209.20 km. The strength of the earthquake may have been tempered by its relative great depth below the surface, which makes it feel weaker in absolute terms. The exact magnitude, epicenter, and depth of the quake might be revised within the next few hours or minutes as seismologists review data and refine their calculations, or as other agencies issue their report.
Towns or cities near the epicenter where the quake might have been felt as very weak shaking include Kamoenai (pop. 900) located 68 km from the epicenter, Iwanai (pop. 15,600) 84 km away, Minatomachi (pop. 22,800) 89 km away, Otaru (pop. 115,300) 107 km away, and Ishikari (pop. 57,300) 133 km away.
