NOAA’s list of significant earthquakes has 30 here, back to 1556. NOAA records deaths in 13 of the events here, 85,189 in all. The latest on NOAA’s list is a magnitude 5.7 on July 25, 2022 (9 km N of San Gabriel, Ecuador). NOAA’s record here begins on October 17, 1556 with an earthquake. 19 of the 30 significant earthquakes NOAA lists here came before 1927. NOAA lists 4 significant eruptions of 2 volcanoes within 100 km of Ibarra. The largest was Guagua Pichincha on October 27, 1660, at 4 on the volcanic explosivity index.

Good to know

  • An event counts for Ibarra 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.
