Magnitude 5.2 earthquake strikes near Kushiro, Japan
5.2 quake 16 Dec 10:28 am (GMT +9)
5.2 quake 16 Dec 10:28 am (GMT +9)
Japan was shaken near Kushiro, Kushiro Shi, Hokkaido, by an earthquake of magnitude 5.2 only 14 minutes ago, the European-Mediterranean Seismological Centre (EMSC) reported.
The quake hit at a moderately shallow depth of 60 km beneath the epicenter near Kushiro, Kushiro Shi, Hokkaido, Japan, in the morning on Wednesday 16 December 2020 at 10:28 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 the German Research Centre for Geosciences (GFZ), which listed it as a magnitude 5.5 earthquake.
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 38 km from the epicenter, Obihiro (pop. 173,900) 94 km away, Otofuke (pop. 40,900) 97 km away, and Nemuro (pop. 31,200) 129 km away.
