On December 27, 2023 at 22:43 UTC, a magnitude 5.1 intermediate depth earthquake struck 50 km SSW of Singaparna, Indonesia, at a depth of 72.2 km and coordinates -7.7769°, 107.9533°. This earthquake was detected by 163 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 402, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 5.1 releases seismic energy equivalent to roughly 674 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.0 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.
