2026-10-20 16:29:38 UTC (1 hour ago) · approx. 10:29 PM UTC+6 local
On October 20, 2026 at 16:29 UTC, a magnitude 5.0 intermediate depth earthquake struck 21 km SW of Meulaboh, Indonesia, at a depth of 75.9 km and coordinates 4.0005°, 95.9930°. This earthquake was detected by 110 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 385, 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.
