2025-04-26 06:33:17 UTC (2025-04-26) · approx. 3:33 PM UTC+9 local
On April 26, 2025 at 06:33 UTC, a magnitude 4.9 shallow crustal earthquake struck 110 km S of Abepura, Indonesia, at a depth of 35.0 km and coordinates -3.5924°, 140.5176°. This earthquake was detected by 49 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.
