4.1 quake 22 Sep 3:24 am (GMT +11)

A magnitude 4.1 earthquake near Wakkanai, Wakkanai Shi, Hokkaido, 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 a great depth of 330 km beneath the epicenter early morning on Wednesday, September 22nd, 2021, at 3:24 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.
According to preliminary calculations, we do not expect that the quake was felt by many people and did not cause any damage. In Makubetsu (pop. 25,900, 75 km away), Wakkanai (pop. 41,600, 81 km away), and Korsakov (pop. 35,100, 89 km away), the quake was probably not felt.
