Earthquakes in St. Vincent & Grenadines, 1927–2026

NOAA lists one tsunami that began in or off St. Vincent & Grenadines, and one from elsewhere that reached it with deaths or a metre of water or more. The highest water NOAA records here was 2 m, on July 24, 1939. NOAA lists 2 significant eruptions of one volcano in or off St. Vincent & Grenadines. The largest was Soufriere St. Vincent on April 9, 2021, at 4 on the volcanic explosivity index. The deadliest was Soufriere St. Vincent on April 13, 1979, which killed 2 people by NOAA’s count.

• An event counts for St. Vincent & Grenadines when it began inside its borders, or at sea within 100 km of its coast (so one can count for two neighbours), or further out, up to 300 km, where St. Vincent & Grenadines is the nearest country.
• 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 St. Vincent & Grenadines, 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.
