Significant earthquake of magnitude 5.2 just reported 30 km southeast of Kushiro, Japan

5.2 quake 20 Nov 6:17 pm (GMT +9)
A moderately shallow magnitude 5.2 earthquake was reported early evening near Kushiro, Kushiro Shi, Hokkaido, Japan.
According to Japan's National Research Institute for Earth Science and Disaster Resilience (NIED), the quake hit on Sunday, November 20th, 2022, at 6:17 pm local time at a moderately shallow depth of 57.4 km. 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 the German Research Centre for Geosciences (GFZ), which listed it as a magnitude 5.0 earthquake. Other agencies reporting the same quake include France's Réseau National de Surveillance Sismique (RéNaSS) at magnitude 5.1, the citizen-seismograph network of RaspberryShake at magnitude 4.7, and the European-Mediterranean Seismological Centre (EMSC) at magnitude 4.7.
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 should not have caused any significant damage, but was probably felt by many people as light vibration in the area of the epicenter.
Weak shaking might have been felt in Kushiro (pop. 183,600) located 30 km from the epicenter, Nemuro (pop. 31,200) 83 km away, Shibetsu (pop. 21,700) 89 km away, Motomachi (pop. 23,000) 114 km away, Kitami (pop. 113,100) 120 km away, Obihiro (pop. 173,900) 124 km away, Otofuke (pop. 40,900) 125 km away, and Abashiri (pop. 42,500) 129 km away.
VolcanoDiscovery will automatically update magnitude and depth if these change and follow up if other significant news about the quake become available.
