Significant magnitude 5.1 quake hits 85 km northeast of Hachinohe, Japan in the morning

5.1 quake 17 Nov 9:28 am (GMT +9)

A magnitude 5.1 earthquake near Hachinohe, Hachinohe Shi, Aomori, Japan, was reported only 17 minutes ago by the German Research Centre for Geosciences (GFZ), considered one of the key international agencies that monitor seismic activity worldwide. The earthquake occurred at a shallow depth of 10 km beneath the epicenter in the morning on Thursday, November 17th, 2022, at 9:28 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 France's Réseau National de Surveillance Sismique (RéNaSS), which listed it as a magnitude 5.5 earthquake. Other agencies reporting the same quake include the citizen-seismograph network of RaspberryShake at magnitude 5.1, and the European-Mediterranean Seismological Centre (EMSC) at magnitude 5.5.
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 Yokohama (pop. 4,400) located 67 km from the epicenter, Mutsu (pop. 49,200) 71 km away, Misawa (pop. 42,800) 75 km away, Hachinohe (pop. 239,000) 85 km away, and Aomori (pop. 298,400) 116 km away.
VolcanoDiscovery will automatically update magnitude and depth if these change and follow up if other significant news about the quake become available.
