2021-10-13 10:51:47 UTC (2021-10-13) · approx. 7:51 PM UTC+9 local
On October 13, 2021 at 10:51 UTC, a magnitude 5.0 intermediate depth earthquake struck near Pulau Pulau Tanimbar, Indonesia, at a depth of 91.5 km and coordinates -7.0998°, 130.0563°.
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.
