Earthquakes in the Philippines — October 2025

104 earthquakes were recorded in the Philippines during October 2025, an average of 3.4 per day.

104 reached magnitude 4 or above and 33 reached magnitude 5 or above. The average focal depth was 67 km.

The month's largest event in the Philippines was a magnitude 7.4 earthquake near Santiago, Philippines on 10 October 2025 at 01:43 UTC. A magnitude 7.4 earthquake radiates roughly 1.9 million tons of TNT equivalent in seismic energy.

That is well above the the Philippines monthly average of 35 events over the period we cover — an unusually active month, and up from the 30 recorded the previous month.

79% of events here are shallow (under 70 km), 17% intermediate (70–300 km) and 4% deep-focus (over 300 km). The mix is dominated by shallow crustal events, with a minority of intermediate-depth activity.

By band, the catalogue holds 71 in the magnitude 4 range, 28 in the magnitude 5 range, 4 in the magnitude 6 range, 1 in the magnitude 7 range.

Activity peaked on 10 October, when 36 events were recorded.

3 event(s) this month carry a USGS link to NOAA tsunami information; the flag does not indicate whether a tsunami occurred.

The month's largest events were M7.4 near Santiago, Philippines on 10 October at 58 km; M6.9 near Santiago, Philippines on 10 October at 10 km; M6.7 near Santiago, Philippines on 10 October at 61 km.

That is 201% above the 35 events the Philippines averages per month across the 21 months on record.
