5.1 quake 10 Jun 6:56 pm (GMT +9)
An earthquake of magnitude 5.1 occurred only 10 minutes ago 95 km northeast of Hachinohe, Japan, Japan's National Research Institute for Earth Science and Disaster Resilience (NIED) reported.
The quake hit at a shallow depth of 16.7 km beneath the epicenter near Hachinohe, Hachinohe Shi, Aomori, Japan, early evening on Thursday 10 June 2021 at 6:56 pm 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 European-Mediterranean Seismological Centre (EMSC), which listed it as a magnitude 4.6 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 Misawa (pop. 42,800) located 94 km from the epicenter, Hachinohe (pop. 239,000) 95 km away, and Mutsu (pop. 49,200) 109 km away.
