2023-11-18 18:42:19 UTC (2023-11-18) · approx. 2:42 AM UTC+8 local
On November 18, 2023 at 18:42 UTC, a magnitude 4.7 shallow crustal earthquake struck 196 km NNW of Palu, Indonesia, at a depth of 24.6 km and coordinates 0.8200°, 119.4683°. This earthquake was detected by 53 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 340, placing it among routine seismic activity.
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.
