Felt by 8 people across nearby locations.
On February 13, 2024 at 01:22 UTC, a magnitude 4.9 shallow crustal earthquake struck 25 km NE of Martapura, Indonesia, at a depth of 13.6 km and coordinates -3.2606°, 115.0429°. This earthquake was detected by 88 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.
