Felt by 3 people across nearby locations.
On July 22, 2026 at 04:18 UTC, a magnitude 5.0 shallow crustal earthquake struck 55 km WSW of Langsa, Indonesia, at a depth of 10.0 km and coordinates 4.2441°, 97.5238°. This earthquake was detected by 62 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 386, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.0 releases seismic energy equivalent to roughly 477 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.7 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.
