The latest on NOAA’s list is a magnitude 7 on July 27, 2022 (11 km NE of Bantay, Philippines). NOAA’s record here begins in November 1610 with an earthquake (Luzon: E). It grows thinner going back: 7 of the 11 significant earthquakes NOAA lists here are from 1927 on. NOAA lists 2 tsunamis that began within 100 km of Ilagan. The highest of them reached 0.16 m, on August 1, 1968. The deadliest, on August 1, 1968, killed one person here by NOAA’s runup records. NOAA lists one significant eruption of one volcano within 100 km of Ilagan. The largest was Ambalatungan Group in 1952, at 1 on the volcanic explosivity index. It killed 12 people by NOAA’s count.

Good to know

  • An event counts for Ilagan 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.
