2025-08-07 15:28:59 UTC (2025-08-07) · approx. 10:28 PM UTC+7 local
On August 7, 2025 at 15:28 UTC, a magnitude 5.0 intermediate depth earthquake struck 35 km W of Padangsidempuan, Indonesia, at a depth of 95.9 km and coordinates 1.3202°, 98.9615°. This earthquake was detected by 94 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.
