What the record holds

The deadliest was not the strongest: a magnitude 7.5 on April 18, 1907 (7 km N of Luklukan, Philippines), for which NOAA records 2 deaths. NOAA’s list of significant earthquakes has 15 here, back to 1628. NOAA records deaths in 15 of the events here, 4,721 in all. The latest on NOAA’s list is a magnitude 7.1 on January 11, 1982 (4 km SW of Gigmoto, Philippines). NOAA’s record here begins in 1628 with an earthquake (Luzon: Camalig, Albay). 13 of the 15 significant earthquakes NOAA lists here came before 1927. NOAA lists 2 tsunamis that began within 100 km of Naga. The highest of them reached 1.3 m, on March 17, 1973. NOAA lists 19 significant eruptions of one volcano within 100 km of Naga. The largest was Mayon on February 1, 1814, at 4 on the volcanic explosivity index. The deadliest was Mayon in 1875, which killed 1,500 people by NOAA’s count.

The events

Good to know

  • An event counts for Naga 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.
