4.5 quake 10 Aug 12:48 am (GMT +9)

A magnitude 4.5 earthquake near Miyako, Miyako-shi, Iwate, Japan, was reported only 12 minutes ago by Japan's National Research Institute for Earth Science and Disaster Resilience (NIED), considered the main national agency that monitors seismic activity in this part of the world. The earthquake occurred at a moderately shallow depth of 58.1 km beneath the epicenter after midnight on Wednesday, August 10th, 2022, at 12:48 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 4.1.
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 Iwaizumi (pop. 9,000) located 11 km from the epicenter, and Miyako (pop. 51,700) 15 km away.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Yamada (pop. 20,100) located 34 km from the epicenter, Ōtsuchi (pop. 16,500) 44 km away, Kamaishi (pop. 43,100) 54 km away, Tōno (pop. 26,800) 56 km away, Morioka (pop. 295,200) 59 km away, and Ichinohe (pop. 15,800) 69 km away.
