Felt by 17 people across nearby locations.
On September 24, 2022 at 20:32 UTC, a magnitude 4.9 intermediate depth earthquake struck 106 km S of Muncar, Indonesia, at a depth of 74.1 km and coordinates -9.3953°, 114.3631°. This earthquake was detected by 107 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 375, 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.
