Magnitude 4.2 earthquake strikes near Nemuro, Nemuro-shi, Hokkaido, Japan
4.2 quake 7 Apr 1:44 am (GMT +9)
4.2 quake 7 Apr 1:44 am (GMT +9)
A magnitude 4.2 earthquake near Nemuro, Nemuro-shi, Hokkaido, Japan, was reported only 13 minutes ago by the European-Mediterranean Seismological Centre (EMSC), considered one of the key international agencies that monitor seismic activity worldwide. The earthquake occurred at a moderately shallow depth of 50 km beneath the epicenter early morning on Wednesday 7 April 2021 at 1:44 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.
Our monitoring service identified a second report from Japan's National Research Institute for Earth Science and Disaster Resilience (NIED) which listed the quake at magnitude 4.7.
Towns or cities near the epicenter where the quake might have been felt as very weak shaking include Nemuro (pop. 31,200) located 25 km from the epicenter, Shibetsu (pop. 21,700) 73 km away, and Kushiro (pop. 183,600) 101 km away.
