Magnitude 4.9 earthquake strikes near Kashima-shi, Ibaraki, Japan

4.9 quake 6 Aug 9:23 pm (GMT +9)
4.9 quake 6 Aug 9:23 pm (GMT +9)
Just 13 minutes ago, a 4.9-magnitude earthquake struck near Kashima-shi, Ibaraki, Japan. The tremor was recorded in the evening on Saturday, August 6th, 2022, at 9:23 pm local time, at a shallow depth of 28.3 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.
A second report was later issued by France's Réseau National de Surveillance Sismique (RéNaSS), which listed it as a magnitude 5.2 earthquake. Other agencies reporting the same quake include the citizen-seismograph network of RaspberryShake at magnitude 5.0, the European-Mediterranean Seismological Centre (EMSC) at magnitude 4.9, and the German Research Centre for Geosciences (GFZ) at magnitude 5.0.
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 Kashima-shi (pop. 65,800) located 48 km from the epicenter, Ōarai (pop. 19,300) 49 km away, Katsuta (pop. 156,000) 56 km away, Hitachi-Naka (pop. 156,800) 56 km away, Hasaki (pop. 39,200) 56 km away, Hitachi (pop. 186,300) 61 km away, Katori-shi (pop. 83,200) 63 km away, and Нарита (pop. 100,600) 84 km away.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Chiba (pop. 919,700) located 110 km from the epicenter.
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.
