4.5 quake 24 May 1:27 am (GMT +9)

A magnitude 4.5 earthquake near Akita, Akita Shi, Japan, was reported only 11 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 an intermediate to considerable depth of 174.5 km beneath the epicenter early morning on Monday 24 May 2021 at 1:27 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.
Towns or cities near the epicenter where the quake might have been felt as very weak shaking include Akita (pop. 320,100) located 33 km from the epicenter, Tennō (pop. 22,700) 45 km away, Yuza (pop. 17,100) 56 km away, Ōmagari (pop. 38,800) 56 km away, Yokote (pop. 39,200) 65 km away, Sakata (pop. 100,400) 66 km away, Yuzawa (pop. 33,500) 69 km away, and Tsuruoka (pop. 99,800) 88 km away.
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.
