A moderate earthquake of M6.5 occurred in Kumamoto Prefecture, Kyushu, southwestern Japan, at 21:26 JST on April 14, 2016. It was generated on a right-lateral strike-slip fault, northern part of the Hinagu fault zone. Depth of the epicenter was shallow (about 11 km in depth; JMA), and very strong ground motion was recorded near the source fault. A larger earthquake of M7.3 occurred at 1:25 JST on April 16, 2022 on the Futagawa fault zone, which is the northern neighbor of the Hinagu fault zone.
The Geological Survey of Japan (GSJ) set up the Emergency Survey Headquarters on April 15 to conduct systematic responses.
