Earthquakes in the Philippines — September 2026

16 earthquakes were recorded in the Philippines during September 2026, an average of 0.5 per day.

16 reached magnitude 4 or above and 3 reached magnitude 5 or above. The average focal depth was 51 km.

The month's largest event in the Philippines was a magnitude 5.3 earthquake near Sarangani, Philippines on 21 September 2026 at 23:48 UTC. A magnitude 5.3 earthquake radiates roughly 1,344 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 51 recorded the previous month.

69% of events here are shallow (under 70 km), 31% intermediate (70–300 km) and 0% deep-focus (over 300 km). A substantial share of intermediate-depth events points to a subducting slab beneath the region rather than purely crustal faulting.

By band, the catalogue holds 13 in the magnitude 4 range, 3 in the magnitude 5 range.

Activity peaked on 28 September, when 3 events were recorded.

The month's largest events were M5.3 near Sarangani, Philippines on 21 September at 10 km; M5.2 near Sarangani, Philippines on 01 September at 121 km; M5.0 near Sarangani, Philippines on 09 September at 10 km.

That is 52% below the 33 events the Philippines averages per month across the 23 months on record.
