4.4 quake 18 Jul 6:50 pm (GMT +9)

Japan's National Research Institute for Earth Science and Disaster Resilience (NIED) reported a magnitude 4.4 quake in Japan near Numata, Gunma, only 13 minutes ago. The earthquake hit early evening on Sunday 18 July 2021 at 6:50 pm local time at a very shallow depth of 3.7 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 European-Mediterranean Seismological Centre (EMSC) which listed the quake at magnitude 4.7.
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 Shiozawa (pop. 20,200) located 38 km from the epicenter, Nikkō (pop. 16,000) 45 km away, Tōkamachi (pop. 41,100) 46 km away, Numata (pop. 45,500) 49 km away, and Imaichi (pop. 64,300) 51 km away.

Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Nagaoka (pop. 195,300) located 59 km from the epicenter, Kanuma (pop. 94,900) 68 km away, and Maebashi (pop. 282,700) 73 km away.
