Moderate 4.4 quake hits near Ushiku, Ushiku-shi, Ibaraki, Japan

4.4 quake 2 Jun 4:42 am (GMT +9)

Japan's National Research Institute for Earth Science and Disaster Resilience (NIED) reported a magnitude 4.4 quake in Japan near Ushiku, Ushiku-shi, Ibaraki, only 11 minutes ago. The earthquake hit early morning on Thursday, June 2nd, 2022, at 4:42 am local time at a moderately shallow depth of 61.7 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.
A second report was later issued by the European-Mediterranean Seismological Centre (EMSC), which listed it as a magnitude 4.2 earthquake.
Towns or cities near the epicenter where the quake might have been felt as very weak shaking include Naka (pop. 46,800) located 3 km from the epicenter, Ami (pop. 48,300) 4 km away, Ushiku (pop. 80,000) 7 km away, Ryūgasaki (pop. 85,800) 14 km away, Torite (pop. 80,700) 15 km away, Moriya (pop. 56,600) 18 km away, Tsukuba (pop. 175,600) 20 km away, Mito (pop. 246,500) 45 km away, Tokyo (pop. 8,336,600) 56 km away, and Yokohama (pop. 3,574,400) 80 km away.
