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. NOAA’s list of significant earthquakes has 10 here, back to 1647. NOAA records deaths in 6 of the events here, 31,840 in all. The latest on NOAA’s list is a magnitude 7.1 on March 25, 2012 (23 km NE of Constitución, Chile). NOAA’s record here begins on May 14, 1647 with an earthquake (Santiago). It grows thinner going back: 6 of the 10 significant earthquakes NOAA lists here are from 1927 on. NOAA lists 2 tsunamis that began within 100 km of Curicó, and 2 from elsewhere that reached it with deaths or a metre of water or more. The highest water NOAA records here was 10.5 m, on February 27, 2010.

Good to know

  • An event counts for Curicó 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.
