Earthquakes in Timor-Leste — April 2026

10 earthquakes were recorded in Timor-Leste during April 2026, an average of 0.3 per day.

10 reached magnitude 4 or above and 2 reached magnitude 5 or above. The average focal depth was 173 km.

The month's largest event in Timor-Leste was a magnitude 5.5 earthquake near Pante Makasar, Timor-Leste on 21 April 2026 at 03:17 UTC. A magnitude 5.5 earthquake radiates roughly 2,682 tons of TNT equivalent in seismic energy.

That is close to the Timor-Leste monthly average of 9 events over the period we cover, and down from the 11 recorded the previous month.

10% of events here are shallow (under 70 km), 70% intermediate (70–300 km) and 20% 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 8 in the magnitude 4 range, 2 in the magnitude 5 range.

Activity peaked on 24 April, when 2 events were recorded.

The month's largest events were M5.5 near Pante Makasar, Timor-Leste on 21 April at 77 km; M5.2 near Maubara, Timor-Leste on 20 April at 183 km; M4.6 near Lospalos, Timor-Leste on 23 April at 141 km.

That is 16% above the 9 events Timor-Leste averages per month across the 21 months on record.
