Earthquakes near Naga, 1927–2026

It was also the deadliest: NOAA records one death for it. 2 earthquakes here in these years are on NOAA’s list of significant earthquakes. NOAA records deaths in 7 of the events here, 1,568 in all. The ten years with the most magnitude 6+ earthquakes were 1937–1946, with 5 of the 11. The latest on NOAA’s list is a magnitude 7.1 on January 11, 1982 (4 km SW of Gigmoto, Philippines). NOAA lists one tsunami that began within 100 km of Naga. It reached 1.3 m, on March 17, 1973. NOAA lists 10 significant eruptions of one volcano within 100 km of Naga. The largest was Mayon in January 1928, at 3 on the volcanic explosivity index. The deadliest was Mayon on November 30, 2006, which killed 1,266 people by NOAA’s count.

• 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.
