4.3 quake 12 km south of Kumamoto, Japan, 6 May 2021 9:16 am (GMT +9)
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.
Weak shaking might have been felt in Kumamoto (pop. 680,400) located 12 km from the epicenter, Uekimachi-mōno (pop. 31,700) 23 km away, Honmachi (pop. 104,300) 24 km away, Ōzu (pop. 29,800) 25 km away, Yamaga (pop. 32,300) 36 km away, and Omuta (pop. 132,000) 45 km away.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Fukuoka (pop. 1,392,300) located 104 km from the epicenter.
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.
