M5.2 Earthquake 130 km NE of Maumere, Indonesia — December 7, 2021
2021-12-07 16:26:26 UTC (2021-12-07) · approx. 12:26 AM UTC+8 local
On December 7, 2021 at 16:26 UTC, a magnitude 5.2 intermediate depth earthquake struck 130 km NE of Maumere, Indonesia, at a depth of 267.7 km and coordinates -7.8284°, 123.0860°.
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.
