What the record holds

The deadliest was not the strongest: a magnitude 6 on October 30, 1930 (Senigallia), for which NOAA records 18 deaths. NOAA’s list of significant earthquakes has 8 here, back to 1690. NOAA records deaths in 5 of the events here, 35 in all. The latest on NOAA’s list is a magnitude 4.4 on June 21, 1972 (Ancona). NOAA’s record here begins on December 23, 1690 with an earthquake (Ancona). 4 of the 8 significant earthquakes NOAA lists here came before 1927. NOAA lists 3 tsunamis that began in or off San Marino.

Good to know

  • An event counts for San Marino 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 San Marino 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 San Marino, 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.
