A moderately shallow magnitude 4.7 earthquake was reported in the morning near Kashima-shi, Ibaraki, Japan.
According to Japan's National Research Institute for Earth Science and Disaster Resilience (NIED), the quake hit on Sunday, September 18th, 2022, at 11:09 am local time at a moderately shallow depth of 38.9 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.
Our monitoring service identified a second report from the citizen-seismograph network of RaspberryShake which listed the quake at magnitude 5.0. Other agencies reporting the same quake include the German Research Centre for Geosciences (GFZ) at magnitude 5.0, the European-Mediterranean Seismological Centre (EMSC) at magnitude 4.8, and France's Réseau National de Surveillance Sismique (RéNaSS) 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 Omigawa (pop. 25,800) located 3 km from the epicenter, Itako (pop. 25,800) 9 km away, Kashima-shi (pop. 65,800) 10 km away, Sawara (pop. 47,200) 10 km away, Katori-shi (pop. 83,200) 11 km away, Нарита (pop. 100,600) 29 km away, Ryūgasaki (pop. 85,800) 39 km away, and Mito (pop. 246,500) 55 km away.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Tokyo (pop. 8,336,600) located 86 km from the epicenter, and Yokohama (pop. 3,574,400) 100 km away.
