Significant earthquake of magnitude 5.8 just reported 32 km south of Nemuro, Japan

An earthquake of magnitude 5.8 occurred only 11 minutes ago 32 km south of Nemuro, Japan, the European-Mediterranean Seismological Centre (EMSC) reported.
The quake hit at a moderately shallow depth of 46. km beneath the epicenter near Nemuro, Nemuro-shi, Hokkaido, Japan, early morning on Saturday, October 25th, 2025, at 1:40 am local time. 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.
A second report was later issued by France's Réseau National de Surveillance Sismique (RéNaSS), which listed it as a magnitude 5.5 earthquake. A third agency, the German Research Centre for Geosciences (GFZ), reported the same quake at magnitude 5.7.
Based on the preliminary seismic data, the quake was probably felt by many people in the area of the epicenter. It should not have caused significant damage, other than objects falling from shelves, broken windows, etc.
In Nemuro (pop. 31,200) located 32 km from the epicenter, Hamanaka-sakuraminami (pop. 5,500) 36 km away, Akkeshi (pop. 8,900) 54 km away, Nakashibetsu (pop. 24,000) 71 km away, Shibetsu (pop. 21,700) 75 km away, Shibecha (pop. 7,200) 82 km away, and Kushiro (pop. 167,900) 93 km away, the quake should have been felt as light shaking.
