2024-03-04 06:55:13 UTC (2024-03-04) · approx. 1:55 PM UTC+7 local
On March 4, 2024 at 06:55 UTC, a magnitude 4.9 shallow crustal earthquake struck 104 km SSW of Pagar Alam, Indonesia, at a depth of 63.2 km and coordinates -4.8792°, 102.8413°. This earthquake was detected by 99 seismic stations with good 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.
