Just 12 minutes ago, a 4.9-magnitude earthquake struck near Mutsu, Mutsu-shi, Aomori, Japan. The tremor was recorded early evening on Thursday, April 28th, 2022, at 7:03 pm local time, at a shallow depth of 21.7 km below the surface.
The event was filed by Japan's National Research Institute for Earth Science and Disaster Resilience (NIED), the first seismological agency to report it.
Our monitoring service identified a second report from the European-Mediterranean Seismological Centre (EMSC) which listed the quake at magnitude 4.6.
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 97 km from the epicenter, Mutsu (pop. 49,200) 97 km away, and Hachinohe (pop. 239,000) 103 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.
