Earthquakes in the Philippines — January 2025

25 earthquakes were recorded in the Philippines during January 2025, an average of 0.8 per day.

25 reached magnitude 4 or above and 8 reached magnitude 5 or above. The average focal depth was 102 km.

The month's largest event in the Philippines was a magnitude 5.7 earthquake near Liloan, Philippines on 22 January 2025 at 23:39 UTC. A magnitude 5.7 earthquake radiates roughly 5,351 tons of TNT equivalent in seismic energy.

That is below the the Philippines monthly average of 33 events over the period we cover — a comparatively quiet month, and down from the 29 recorded the previous month.

52% of events here are shallow (under 70 km), 40% intermediate (70–300 km) and 8% deep-focus (over 300 km). That proportion of deep-focus events is the signature of a subduction zone: only a cold slab descending into the mantle stays brittle enough to rupture at those depths.

By band, the catalogue holds 17 in the magnitude 4 range, 8 in the magnitude 5 range.

Activity peaked on 13 January, when 2 events were recorded.

The month's largest events were M5.7 near Liloan, Philippines on 22 January at 9 km; M5.5 near Bantogon, Philippines on 13 January at 545 km; M5.4 near Siocon, Philippines on 23 January at 10 km.

That is 25% below the 33 events the Philippines averages per month across the 22 months on record.
