What the record holds

The deadliest was not the strongest: a magnitude 7.9 on August 16, 1976 (19 km WNW of Palimbang, Philippines), for which NOAA records 8,000 deaths. NOAA’s list of significant earthquakes has 26 here, back to 1878. NOAA records deaths in 15 of the events here, 8,532 in all. The latest on NOAA’s list is a magnitude 7.8 on June 7, 2026 (25 km SW of Kablalan, Philippines). NOAA’s record here begins on September 16, 1878 with an earthquake (Near Mount Apo). 8 of the 26 significant earthquakes NOAA lists here came before 1927. NOAA lists 3 tsunamis that began within 100 km of General Santos, and 3 from elsewhere that reached it with deaths or a metre of water or more. The highest water NOAA records here was 5.5 m, on August 15, 1918. The deadliest, on June 7, 2026, killed 2 people here by NOAA’s runup records. NOAA lists one significant eruption of one volcano within 100 km of General Santos. The deadliest was Melebingoy on September 6, 1995, which killed 60 people by NOAA’s count.

Good to know

  • An event counts for General Santos 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.
