Japan's National Research Institute for Earth Science and Disaster Resilience (NIED) reported a magnitude 4.3 quake in Japan near Hanawa, Kazuno Shi, Akita, only 11 minutes ago. The earthquake hit late at night on Wednesday, December 1st, 2021, at 11:31 pm local time at a shallow depth of 10.9 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 European-Mediterranean Seismological Centre (EMSC), which listed it as a magnitude 4.2 earthquake.
Based on the preliminary seismic data, the quake was probably felt by many people in the area of the epicenter. It should not have caused significant damage, other than objects falling from shelves, broken windows, etc.
In Hanawa (pop. 36,900) located 11 km from the epicenter, the quake should have been felt as light shaking.
Weak shaking might have been felt in Ōdate (pop. 64,500) located 28 km from the epicenter, Ichinohe (pop. 15,800) 34 km away, and Takanosu (pop. 20,500) 45 km away.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Kuroishi (pop. 38,600) located 52 km from the epicenter, Hirosaki (pop. 175,000) 53 km away, Hachinohe (pop. 239,000) 59 km away, Misawa (pop. 42,800) 65 km away, and Akita (pop. 320,100) 88 km away.
VolcanoDiscovery will automatically update magnitude and depth if these change and follow up if other significant news about the quake become available. If you're in the area, please send us your experience through our reporting mechanism, either online or via our mobile app. This will help us provide more first-hand updates to anyone around the globe who wants to know more about this quake.
