Earthquakes in St. Kitts & Nevis through history

NOAA’s list of significant earthquakes has 4 here, back to 1690. NOAA records no deaths for any of them. The latest on NOAA’s list is a magnitude 6.5 on March 16, 1985 (18 km SE of Market Shop, Saint Kitts and Nevis). NOAA’s record here begins on April 16, 1690 with an earthquake. NOAA lists 3 tsunamis that began in or off St. Kitts & Nevis. The highest of them reached 0.12 m, on March 16, 1985. NOAA lists one significant eruption of one volcano in or off St. Kitts & Nevis. The largest was Liamuiga on February 8, 1843, at 0 on the volcanic explosivity index.

• An event counts for St. Kitts & Nevis 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. Kitts & Nevis 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. Kitts & Nevis, 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.
