What the record holds

The deadliest was not the strongest: a magnitude 7.1 on October 15, 2013 (4 km SE of Sagbayan, Philippines), for which NOAA records 222 deaths. NOAA’s list of significant earthquakes has 11 here, back to 1620. NOAA records deaths in 5 of the events here, 306 in all. NOAA’s record here begins in 1620 with an earthquake (Panay,Iloilo,Capiz). 7 of the 11 significant earthquakes NOAA lists here came before 1927. NOAA lists one tsunami that began within 100 km of Iloilo, and one from elsewhere that reached it with deaths or a metre of water or more. The highest water NOAA records here was 1 m, on February 6, 2012. The deadliest, on January 24, 1948, killed 2 people here by NOAA’s runup records. NOAA lists 3 significant eruptions of one volcano within 100 km of Iloilo. The largest was Kanlaon on June 3, 2024, at 3 on the volcanic explosivity index.

The events

Good to know

  • An event counts for Iloilo 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.
