Earthquakes near Kurume through history

The deadliest was not the strongest: an estimated magnitude 6.4 on May 21, 1792 (Kyusyu Island), for which NOAA records 15,030 deaths. NOAA’s list of significant earthquakes has 19 here, back to AD 744. NOAA records deaths in 32 of the events here, 19,854 in all. The latest on NOAA’s list is a magnitude 6.8 on July 28, 2026 (The 2026 Kumamoto Region, Japan Earthquake). NOAA’s record here begins in December 1331 with an eruption (Asosan). It grows thinner going back: 9 of the 19 significant earthquakes NOAA lists here are from 1927 on. NOAA lists 6 tsunamis that began within 100 km of Kurume, and 9 from elsewhere that reached it with deaths or a metre of water or more. The highest water NOAA records here was 55 m, on May 21, 1792. The deadliest, on May 21, 1792, killed 4,343 people here by NOAA’s runup records. NOAA lists 21 significant eruptions of 2 volcanoes within 100 km of Kurume. The largest was Asosan in December 1872, at 3 on the volcanic explosivity index. It killed 4 people by NOAA’s count.

• An event counts for Kurume when it began within 100 km of its centre, or 200 km for an earthquake of magnitude 7 or more. Damage can reach further.
• USGS counts here start at magnitude 6: the catalogue’s smaller quakes thin out going back, where few instruments listened.
• NOAA lists significant events only: earthquakes that killed, did about $1 million of damage, reached magnitude 7.5 or intensity X, or raised a tsunami, and eruptions and tsunamis by like measures. Magnitudes before 1900 are its estimates from written accounts.
• Deaths are NOAA’s total for each event, wherever people died, its tsunami and fires included. A tsunami counts the dead its runup records give for this place: NOAA’s total for a tsunami includes its source quake’s.
• A tsunami from elsewhere counts where one of its runups killed or rose a metre or more.
• Counted to October 19, 2026, as is the map. The last 30 days ask USGS again.
