M4.6 Earthquake 95 km SW of Pagar Alam, Indonesia — July 11, 2020
2020-07-11 20:54:32 UTC (2020-07-11) · approx. 3:54 AM UTC+7 local
On July 11, 2020 at 20:54 UTC, a magnitude 4.6 shallow crustal earthquake struck 95 km SW of Pagar Alam, Indonesia, at a depth of 61.4 km and coordinates -4.7265°, 102.7487°.
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.
