M5.1 Earthquake 100 km W of Pariaman, Indonesia — February 22, 2026
2026-02-22 15:35:41 UTC (2026-02-22) · approx. 10:35 PM UTC+7 local
On February 22, 2026 at 15:35 UTC, a magnitude 5.1 shallow crustal earthquake struck 100 km W of Pariaman, Indonesia, at a depth of 50.4 km and coordinates -0.6891°, 99.2171°. This earthquake was detected by 78 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 400, 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.
