2025-06-06 14:41:59 UTC (2025-06-06) · approx. 10:41 PM UTC+8 local
On June 6, 2025 at 14:41 UTC, a magnitude 4.5 intermediate depth earthquake struck 38 km SW of Sape, Indonesia, at a depth of 112.9 km and coordinates -8.8381°, 118.7623°. This earthquake was detected by 35 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 312, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.5 releases seismic energy equivalent to roughly 85 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 767 m — 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.
