2026-08-25 06:48:20 UTC (41 min ago) · approx. 2:48 PM UTC+8 local
On August 25, 2026 at 06:48 UTC, a magnitude 4.6 deep-focus earthquake struck 218 km NNW of Manado, Indonesia, at a depth of 322.9 km and coordinates 3.4176°, 124.4529°. This earthquake was detected by 80 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 326, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.6 releases seismic energy equivalent to roughly 120 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 899 m — 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.
