Earthquakes near Koronadal through history

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 24 here, back to 1870. NOAA records deaths in 14 of the events here, 8,524 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 November 4, 1870 with an earthquake (Mindanao: Davao,Blanco). 9 of the 24 significant earthquakes NOAA lists here came before 1927. NOAA lists 5 tsunamis that began within 100 km of Koronadal, and 2 from elsewhere that reached it with deaths or a metre of water or more. The highest water NOAA records here was 9 m, on August 16, 1976. The deadliest here came on August 15, 1918 from a magnitude 8.3 earthquake (Celebes Sea): NOAA’s runup records count 6 deaths within 100 km of Koronadal. NOAA lists one significant eruption of one volcano within 100 km of Koronadal. The deadliest was Melebingoy on September 6, 1995, which killed 60 people by NOAA’s count.

• An event counts for Koronadal 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.
