Just 13 minutes ago, a 5.3-magnitude earthquake struck near Shizunai-furukawachō, Hidaka-gun, Hokkaido, Japan. The tremor was recorded early morning on Tuesday, December 21st, 2021, at 1:05 am local time, at a moderately shallow depth of 42.8 km below the surface.
The event was filed by Japan's National Research Institute for Earth Science and Disaster Resilience (NIED), the first seismological agency to report it.
A second report was later issued by the European-Mediterranean Seismological Centre (EMSC), which listed it as a magnitude 4.9 earthquake. Other agencies reporting the same quake include the German Research Centre for Geosciences (GFZ) at magnitude 5.0, and France's Réseau National de Surveillance Sismique (RéNaSS) at magnitude 5.2.
Generally quakes of this magnitude are recorded by more than one agency and the results can vary, with subsequent reports that come in after the first one often showing more accuracy.
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 Shizunai-furukawachō (pop. 22,400) located 23 km from the epicenter, the quake should have been felt as light shaking.
Weak shaking might have been felt in Obihiro (pop. 173,900) located 76 km from the epicenter, Otofuke (pop. 40,900) 82 km away, Tomakomai (pop. 174,800) 90 km away, Chitose (pop. 92,900) 94 km away, Kitahiroshima (pop. 62,400) 110 km away, Iwamizawa (pop. 85,100) 116 km away, Ebetsu (pop. 134,000) 120 km away, and Sapporo (pop. 1,883,000) 130 km away.
