Felt by 19 people across nearby locations. Maximum shaking intensity MMI 8.3 (violent).
On August 14, 2026 at 21:58 UTC, a magnitude 7.7 shallow crustal earthquake struck 68 km NNW of Ende, Indonesia, at a depth of 10.0 km and coordinates -8.3101°, 121.3517°. The earthquake was reported felt by 19 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 8.3 (violent). The USGS PAGER system issued a yellow alert level for this event, indicating local impact possible. This earthquake was detected by 107 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 923, making it one of the more significant events of the week. The nearest populated place is Ende (population 87,269).
Physical scale: An earthquake of magnitude 7.7 releases seismic energy equivalent to roughly 5.4 megatons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 124 km — a useful intuition for the size of the slip patch on the fault.
The epicenter is located in Indonesia, a region characterized by the convergence of the Indo-Australian, Eurasian, and Philippine Sea plates, forming the Sunda-Banda arc system. The nearest mapped fault system is the Sunda megathrust. View all earthquakes in Indonesia.

Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 7.7 earthquakes can continue for months to years and gradually diminish over time.
Has Indonesia had earthquakes this big before?
The largest recorded earthquake in Indonesia was the M9.1 Indian Ocean earthquake of December 26, 2004. Today's magnitude 7.7 event is significantly smaller than that historical record.
