M4.7 Earthquake 293 km SSW of Pagar Alam, Indonesia — December 15, 2020
2020-12-15 09:55:43 UTC (2020-12-15) · approx. 4:55 PM UTC+7 local
On December 15, 2020 at 09:55 UTC, a magnitude 4.7 shallow crustal earthquake struck 293 km SSW of Pagar Alam, Indonesia, at a depth of 10.0 km and coordinates -6.5216°, 102.3583°.
Physical scale: An earthquake of magnitude 4.7 releases seismic energy equivalent to roughly 169 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.1 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.
