2021-11-10 15:09:48 UTC (2021-11-10) · approx. 11:09 PM UTC+8 local
On November 10, 2021 at 15:09 UTC, a magnitude 4.6 intermediate depth earthquake struck 137 km NNW of Tobelo, Indonesia, at a depth of 78.1 km and coordinates 2.8491°, 127.4723°.
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.
