Earthquakes in U.S. Virgin Islands through history

It was also the deadliest: NOAA records 24 deaths for it. NOAA’s list of significant earthquakes has 7 here, back to 1837. The latest on NOAA’s list is an earthquake on March 11, 1874. NOAA’s record here begins on August 2, 1837 with an earthquake. 7 of the 7 significant earthquakes NOAA lists here came before 1927. NOAA lists 3 tsunamis that began in or off U.S. Virgin Islands, and 2 from elsewhere that reached it with deaths or a metre of water or more. The highest water NOAA records here was 15.2 m, on November 18, 1867. The deadliest, on November 18, 1867, killed 24 people here by NOAA’s runup records.

• An event counts for U.S. Virgin Islands 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 U.S. Virgin Islands 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 U.S. Virgin Islands, 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.
