2023-11-16 02:21:48 UTC (2023-11-16) · approx. 11:21 AM UTC+9 local
On November 16, 2023 at 02:21 UTC, a magnitude 5.1 intermediate depth earthquake struck 203 km NNE of Agats, Indonesia, at a depth of 93.3 km and coordinates -3.7850°, 138.6740°. This earthquake was detected by 90 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 400, 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.
