2023-09-13 05:34:33 UTC (2023-09-13) · approx. 12:34 PM UTC+7 local
On September 13, 2023 at 05:34 UTC, a magnitude 5.0 deep-focus earthquake struck 100 km NW of Batang, Indonesia, at a depth of 650.7 km and coordinates -5.7540°, 110.1746°. This earthquake was detected by 131 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 385, placing it among routine seismic activity.
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.
