Earthquakes in Timor-Leste — September 2026
9 earthquakes were recorded in Timor-Leste during September 2026, an average of 0.3 per day.
9 reached magnitude 4 or above and 3 reached magnitude 5 or above. The average focal depth was 173 km.
The month's largest event in Timor-Leste was a magnitude 5.9 earthquake near Lospalos, Timor-Leste on 11 September 2026 at 11:56 UTC. A magnitude 5.9 earthquake radiates roughly 10,676 tons of TNT equivalent in seismic energy.
That is close to the Timor-Leste monthly average of 8 events over the period we cover, and up from the 8 recorded the previous month.
33% of events here are shallow (under 70 km), 44% intermediate (70–300 km) and 22% 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, 3 in the magnitude 5 range.
Activity peaked on 19 September, when 2 events were recorded.
The month's largest events were M5.9 near Lospalos, Timor-Leste on 11 September at 112 km; M5.3 near Lospalos, Timor-Leste on 10 September at 10 km; M5.0 near Metinaro, Timor-Leste on 25 September at 10 km.
That is close to the 8 events Timor-Leste averages per month across the 23 months on record.
