2022-11-15 17:22:07 UTC (2022-11-15) · approx. 12:22 AM UTC+7 local
On November 15, 2022 at 17:22 UTC, a magnitude 4.9 shallow crustal earthquake struck 66 km SW of Labuan, Indonesia, at a depth of 33.9 km and coordinates -6.8267°, 105.4276°. This earthquake was detected by 109 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 369, placing it among routine seismic activity.
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.
