2025-02-25 18:13:49 UTC (2025-02-25) · approx. 2:13 AM UTC+8 local
On February 25, 2025 at 18:13 UTC, a magnitude 5.1 shallow crustal earthquake struck 209 km NW of Tobelo, Indonesia, at a depth of 47.0 km and coordinates 2.9535°, 126.5765°. This earthquake was detected by 103 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 400, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.1 releases seismic energy equivalent to roughly 674 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.0 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.
