What the record holds

The one on February 4, 1976 was the deadliest: NOAA records 23,000 deaths for it. NOAA’s list of significant earthquakes has 7 here, back to 1539. NOAA records deaths in 3 of the events here, 23,004 in all. The latest on NOAA’s list is a magnitude 5.4 on April 10, 2013 (Atlantida). NOAA’s record here begins on November 24, 1539 with an earthquake (Cabo De Higueras). It grows thinner going back: 4 of the 7 significant earthquakes NOAA lists here are from 1927 on. NOAA lists 2 tsunamis that began within 100 km of Puerto Cortez, and one from elsewhere that reached it with deaths or a metre of water or more. The highest water NOAA records here was 5 m, on August 4, 1856.

Good to know

  • An event counts for Puerto Cortez 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.
