Earthquakes in Indonesia — June 2025

54 earthquakes were recorded in Indonesia during June 2025, an average of 1.8 per day.

54 reached magnitude 4 or above and 4 reached magnitude 5 or above. The average focal depth was 66 km.

The month's largest event in Indonesia was a magnitude 5.3 earthquake near Tobelo, Indonesia on 28 June 2025 at 12:40 UTC. A magnitude 5.3 earthquake radiates roughly 1,344 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 62 recorded the previous month.

69% of events here are shallow (under 70 km), 28% intermediate (70–300 km) and 4% 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 50 in the magnitude 4 range, 4 in the magnitude 5 range.

Activity peaked on 17 June, when 5 events were recorded.

The month's largest events were M5.3 near Tobelo, Indonesia on 28 June at 56 km; M5.2 near Fakfak, Indonesia on 04 June at 10 km; M5.2 near Tambolaka, Indonesia on 13 June at 10 km.

That is 23% below the 70 events Indonesia averages per month across the 21 months on record.
