What the record holds

It was also the deadliest: NOAA records 3 deaths for it. NOAA’s list of significant earthquakes has 13 here, back to 1836. NOAA records deaths in 5 of the events here, 40 in all. The latest on NOAA’s list is a magnitude 7.7 on November 14, 2007 (36 km ESE of Tocopilla, Chile). NOAA’s record here begins on July 3, 1836 with an earthquake (Cobija). 4 of the 13 significant earthquakes NOAA lists here came before 1927. NOAA lists 4 tsunamis that began within 100 km of Antofagasta, and 2 from elsewhere that reached it with deaths or a metre of water or more. The highest water NOAA records here was 11.5 m, on May 10, 1877. The deadliest here came on May 10, 1877 from a magnitude 8.3 earthquake (Northern Chile): NOAA’s runup records count 33 deaths within 100 km of Antofagasta.

Good to know

  • An event counts for Antofagasta 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.
