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 13 here, back to 1620. NOAA records deaths in 5 of the events here, 382 in all. The latest on NOAA’s list is a magnitude 6.9 on September 30, 2025 (8 km ESE of Calape, Philippines). NOAA’s record here begins in 1620 with an earthquake (Panay,Iloilo,Capiz). 9 of the 13 significant earthquakes NOAA lists here came before 1927. NOAA lists 2 tsunamis from elsewhere that reached the coast within 100 km of Cadiz with deaths or a metre of water or more. The highest water NOAA records here was 4 m, on February 6, 2012. The deadliest here came on January 24, 1948 from a magnitude 7.8 earthquake (Sulu Sea): NOAA’s runup records count 2 deaths within 100 km of Cadiz. NOAA lists 3 significant eruptions of one volcano within 100 km of Cadiz. The largest was Kanlaon on June 3, 2024, at 3 on the volcanic explosivity index.

The events

Good to know

  • An event counts for Cadiz 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.
