What the record holds

The deadliest was not the strongest: a magnitude 7.9 on January 25, 1939 (26 km WNW of San Carlos, Chile), for which NOAA records 30,000 deaths. 9 earthquakes here in these years are on NOAA’s list of significant earthquakes. NOAA records deaths in 5 of the events here, 32,850 in all. The ten years with the most magnitude 6+ earthquakes were 1957–1966, with 8 of the 18. The latest on NOAA’s list is a magnitude 8.8 on February 27, 2010 (2010 Maule, Chile Earthquake). NOAA lists one tsunami that began within 100 km of Villa Mercedes.

Good to know

  • An event counts for Villa Mercedes when it began within 100 km of its centre, or 200 km for an earthquake of magnitude 7 or more. Damage can reach further.
  • 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.
  • Counted to October 19, 2026, as is the map. The last 30 days ask USGS again.
