2020-10-15 10:34:12 UTC (2020-10-15) · approx. 5:34 PM UTC+7 local
On October 15, 2020 at 10:34 UTC, a magnitude 4.9 shallow crustal earthquake struck 173 km SW of Sungai Penuh, Indonesia, at a depth of 17.4 km and coordinates -3.2190°, 100.3448°.
Physical scale: An earthquake of magnitude 4.9 releases seismic energy equivalent to roughly 338 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.4 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.
