When aftershocks are detected, we will update this section.What are aftershocks?Larger earthquakes (above magnitude 5 or so) such as this one are usually followed by smaller ones known as aftershocks that occur in the same area during the days, weeks, months or even years after the main shock.[More info]What about this quake?Based on its magnitude, the fault that was active during the quake likely ruptured beneath a surface area of approximately 20 km2 (8 square miles) as a first-order estimate. The length of the rupture zone thus was probably around 8 km (5 mi).[More info]Recorded aftershocks, latest first (0 quake)Apr 20, 2026 01:19 pm (GMT +8)11 minutes ago5.3180 km0 km - This quakeBanda Sea, 23 km N of Pulau Pura Island, East Nusa Tenggara, IndonesiaMain Shock (this quake)MoreMap of aftershocksPrevious quakes in the same area of this earthquakeStrongest in 4 yearsThe earthquake was the strongest to hit this part of Indonesia in over 4 years.
