2022-09-07 20:11:12 UTC (2022-09-07) · approx. 4:11 AM UTC+8 local
On September 7, 2022 at 20:11 UTC, a magnitude 4.6 intermediate depth earthquake struck 58 km SSE of Gorontalo, Indonesia, at a depth of 159.3 km and coordinates 0.0276°, 123.1881°. This earthquake was detected by 69 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.
