Felt by 1 person across nearby locations.
On July 12, 2026 at 13:20 UTC, a magnitude 5.1 shallow crustal earthquake struck 27 km SSE of Tambolaka, Indonesia, at a depth of 42.9 km and coordinates -9.6705°, 119.3040°. This earthquake was detected by 53 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 401, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.1 releases seismic energy equivalent to roughly 674 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.0 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.
