Earthquakes in Indonesia — May 2025

62 earthquakes were recorded in Indonesia during May 2025, an average of 2.0 per day.

62 reached magnitude 4 or above and 7 reached magnitude 5 or above. The average focal depth was 83 km.

The month's largest event in Indonesia was a magnitude 6.0 earthquake near Gorontalo, Indonesia on 03 May 2025 at 12:51 UTC. A magnitude 6.0 earthquake radiates roughly 15,080 tons of TNT equivalent in seismic energy.

That is close to the Indonesia monthly average of 70 events over the period we cover, and down from the 72 recorded the previous month.

68% of events here are shallow (under 70 km), 27% intermediate (70–300 km) and 5% 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 55 in the magnitude 4 range, 6 in the magnitude 5 range, 1 in the magnitude 6 range.

Activity peaked on 03 May, when 5 events were recorded.

The month's largest events were M6.0 near Gorontalo, Indonesia on 03 May at 108 km; M5.8 near Blangpidie, Indonesia on 11 May at 95 km; M5.7 near Bengkulu, Indonesia on 22 May at 68 km.

That is 12% below the 70 events Indonesia averages per month across the 21 months on record.
