Earthquakes in Timor-Leste — December 2025

6 earthquakes were recorded in Timor-Leste during December 2025, an average of 0.2 per day.

6 reached magnitude 4 or above and 0 reached magnitude 5 or above. The average focal depth was 210 km.

The month's largest event in Timor-Leste was a magnitude 4.8 earthquake near Lospalos, Timor-Leste on 08 December 2025 at 20:39 UTC. A magnitude 4.8 earthquake radiates roughly 239 tons of TNT equivalent in seismic energy.

That is below the Timor-Leste monthly average of 9 events over the period we cover — a comparatively quiet month, and down from the 10 recorded the previous month.

0% of events here are shallow (under 70 km), 83% intermediate (70–300 km) and 17% 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 6 in the magnitude 4 range.

Activity peaked on 21 December, when 2 events were recorded.

The month's largest events were M4.8 near Lospalos, Timor-Leste on 08 December at 145 km; M4.7 near Lospalos, Timor-Leste on 02 December at 145 km; M4.7 near Metinaro, Timor-Leste on 14 December at 502 km.

That is 31% below the 9 events Timor-Leste averages per month across the 21 months on record.
