Major Earthquakes in Japan Since 2011
Over the years since the March 11, 2011, Great East Japan Earthquake disaster, Japan has had more than 30 major earthquakes measuring lower 6 or higher on the country’s seismic intensity scale.
On July 28, 2026, a magnitude 7.1 earthquake struck Kumamoto Prefecture on Japan's Kyūshū island, according to the Japan Meteorological Agency. The epicenter was shallow at 10 kilometers below the surface, causing violent shaking of level 7 in the cities of Uki and Hikawa, as well as the prefecture's central town. Other areas, such as Minami-ku, Uto, Mashiki, Kamiamakusa, and Kōshi, experienced shaking between levels 6 and upper 6.
Authorities issued a tsunami warning for the Ariake Sea shoreline due to the quake's proximity. Aftershocks followed the initial event, including a magnitude 6.1 tremor at 5:08 pm in the same region. These recent earthquakes are being linked to the March 11, 2011, Great East Japan Earthquake.
