An earthquake of magnitude 4.3 occurred only 10 minutes ago 12 km south of Kumamoto, Japan, Japan's National Research Institute for Earth Science and Disaster Resilience (NIED) reported.
The quake hit at a shallow depth of 12.9 km beneath the epicenter near Kumamoto, Kumamoto Shi, Japan, in the morning on Thursday 6 May 2021 at 9:16 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.
Our monitoring service identified a second report from the European-Mediterranean Seismological Centre (EMSC) which listed the quake at magnitude 4.0.
Based on the preliminary seismic data, the quake was probably felt by many people in the area of the epicenter. It should not have caused significant damage, other than objects falling from shelves, broken windows, etc.
In Uto (pop. 39,200) located 4 km from the epicenter, and Matsubase (pop. 26,200) 7 km away, the quake should have been felt as light shaking.
