A magnitude 4.0 earthquake near Shizuoka, Shizuoka-shi, 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 shallow depth of 23.4 km beneath the epicenter early morning on Wednesday 31 March 2021 at 3:08 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.
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 Shizuoka (pop. 701,600) located 15 km from the epicenter, Fuji (pop. 240,000) 20 km away, and Fujinomiya (pop. 121,500) 21 km away.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Yaizu (pop. 121,100) located 27 km from the epicenter, Numazu (pop. 204,300) 31 km away, Fujieda (pop. 132,900) 31 km away, Mishima (pop. 113,500) 36 km away, and Shimada (pop. 75,800) 41 km away.
