Earthquakes in Timor-Leste — August 2025

13 earthquakes were recorded in Timor-Leste during August 2025, an average of 0.4 per day.

13 reached magnitude 4 or above and 1 reached magnitude 5 or above. The average focal depth was 248 km.

The month's largest event in Timor-Leste was a magnitude 5.4 earthquake near Dili, Timor-Leste on 12 August 2025 at 16:21 UTC. A magnitude 5.4 earthquake radiates roughly 1,898 tons of TNT equivalent in seismic energy.

That is well above the Timor-Leste monthly average of 9 events over the period we cover — an unusually active month, and down from the 14 recorded the previous month.

0% of events here are shallow (under 70 km), 69% intermediate (70–300 km) and 31% 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 12 in the magnitude 4 range, 1 in the magnitude 5 range.

Activity peaked on 12 August, when 4 events were recorded.

The month's largest events were M5.4 near Dili, Timor-Leste on 12 August at 524 km; M4.8 near Baukau, Timor-Leste on 18 August at 389 km; M4.8 near Pante Makasar, Timor-Leste on 25 August at 107 km.

That is 51% above the 9 events Timor-Leste averages per month across the 21 months on record.
