USGS recorded no earthquake of magnitude 4.5 or more within 100 km of Bayugan in the last 30 days.
What the record holds
The deadliest was not the strongest: a magnitude 7.4 on October 10, 2025 (12 km E of Santiago, Philippines), for which NOAA records 10 deaths. NOAA’s list of significant earthquakes has 18 here, back to 1894. NOAA records deaths in 5 of the events here, 17 in all. NOAA’s record here begins on June 28, 1894 with an earthquake (E Mindanao: Agusan River Valley). 8 of the 18 significant earthquakes NOAA lists here came before 1927.

Good to know
- An event counts for Bayugan 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.
