Magnitude 5.0 earthquake strikes near Aomori, Aomori Shi, Japan

5.0 quake 12 Sep 6:21 am (GMT +9)
5.0 quake 12 Sep 6:21 am (GMT +9)
An earthquake of magnitude 5.0 occurred only 23 minutes ago 65 km northwest of Aomori, Japan, the United States Geological Survey reported.
The quake hit at an intermediate to considerable depth of 166.3 km beneath the epicenter near Aomori, Aomori Shi, Japan, early morning on Monday, September 12th, 2022, at 6:21 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 the European-Mediterranean Seismological Centre (EMSC) which listed the quake at magnitude 5.0 as well. Other agencies reporting the same quake include the citizen-seismograph network of RaspberryShake at magnitude 4.5, the German Research Centre for Geosciences (GFZ) at magnitude 4.5, and Japan's National Research Institute for Earth Science and Disaster Resilience (NIED) at magnitude 5.0.
Generally quakes of this magnitude are recorded by more than one agency and the results can vary, with subsequent reports that come in after the first one often showing more accuracy.
Towns or cities near the epicenter where the quake might have been felt as very weak shaking include Fukushima (pop. 4,400) located 32 km from the epicenter, Shimokizukuri (pop. 18,900) 47 km away, Goshogawara (pop. 49,100) 51 km away, Aomori (pop. 298,400) 65 km away, Kuroishi (pop. 38,600) 72 km away, Hirosaki (pop. 175,000) 73 km away, Hakodate (pop. 275,700) 81 km away, and Mutsu (pop. 49,200) 90 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.
