What the record holds

The deadliest was not the strongest: an estimated magnitude 8.5 on October 20, 1687 (Lima), for which NOAA records 5,000 deaths. NOAA’s list of significant earthquakes has 16 here, back to 1594. NOAA records deaths in 10 of the events here, 6,121 in all. The latest on NOAA’s list is a magnitude 6.4 on January 30, 2012 (6 km ESE of Pampa de Tate, Peru). NOAA’s record here begins on December 18, 1594 with an earthquake (Ica). It grows thinner going back: 8 of the 16 significant earthquakes NOAA lists here are from 1927 on. NOAA lists 2 tsunamis that began within 100 km of Ica, and 3 from elsewhere that reached it with deaths or a metre of water or more. The highest water NOAA records here was 10.05 m, on August 15, 2007. The deadliest here came on August 15, 2007 from a magnitude 8 earthquake (S. Peru): NOAA’s runup records count 3 deaths within 100 km of Ica.

Good to know

  • An event counts for Ica 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.
