2025-08-12 02:14:10 UTC (2025-08-12) · approx. 10:14 AM UTC+8 local
On August 12, 2025 at 02:14 UTC, a magnitude 5.2 intermediate depth earthquake struck 27 km ESE of Gorontalo, Indonesia, at a depth of 273.9 km and coordinates 0.4341°, 123.2841°. This earthquake was detected by 181 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 416, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.2 releases seismic energy equivalent to roughly 951 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.3 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.
