Felt by 6 people across nearby locations.
On March 17, 2023 at 12:05 UTC, a magnitude 5.0 shallow crustal earthquake struck south of Java, Indonesia, at a depth of 49.7 km and coordinates -9.0210°, 109.7511°. This earthquake was detected by 60 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 386, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.0 releases seismic energy equivalent to roughly 477 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.7 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.
