What the record holds

The deadliest was not the strongest: a magnitude 7.5 on April 19, 1902 (Near Quetzaltenango, Guatemala), for which NOAA records 2,000 deaths. NOAA’s list of significant earthquakes has 28 here, back to 1717. NOAA records deaths in 17 of the events here, 12,736 in all. The latest on NOAA’s list is a magnitude 7.3 on July 17, 2026 (60 km WSW of Puerto Madero, Mexico). NOAA’s record here begins on September 29, 1717 with an earthquake (Antigua). It grows thinner going back: 18 of the 28 significant earthquakes NOAA lists here are from 1927 on. NOAA lists 3 tsunamis that began within 100 km of Coatepeque, and one from elsewhere that reached it with deaths or a metre of water or more. The highest water NOAA records here was 2 m, on September 8, 2017. NOAA lists 4 significant eruptions of one volcano within 100 km of Coatepeque. The largest was Santa Maria on October 25, 1902, at 6 on the volcanic explosivity index. It killed 10,000 people by NOAA’s count.

The events

Good to know

  • An event counts for Coatepeque 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.
