An earthquake of magnitude 4.2 occurred after midnight on Sunday, December 5th, 2021, at 12:25 am local time near Naze, Amami Shi, Kagoshima, Japan, as reported by Japan's National Research Institute for Earth Science and Disaster Resilience (NIED).
According to preliminary data, the quake was located at a very shallow depth of 1.5 km. Shallow earthquakes are felt more strongly than deeper ones as they are closer to the surface. 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 Naze (pop. 41,400) located 98 km from the epicenter.
