Earthquakes in Thailand, 1927–2026

It was also the deadliest: NOAA records one death for it. 3 earthquakes here in these years are on NOAA’s list of significant earthquakes. NOAA records deaths in 2 of the events here, 8,213 in all. NOAA lists one tsunami from elsewhere that reached Thailand with deaths or a metre of water or more. The highest water NOAA records here was 19.6 m, on December 26, 2004. The deadliest here came on December 26, 2004 from a magnitude 9.1 earthquake (Off W. Coast Of Sumatra): NOAA’s runup records count 8,212 deaths in Thailand.

• An event counts for Thailand when it began inside its borders. Damage can reach across them.
• 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.
• The map frames the box around Thailand, its neighbours’ quakes included, so its count runs higher than this page’s.
• Counted to October 19, 2026, as is the map. The last 30 days ask USGS again.
