On April 17, 2025 at 04:35 UTC, a magnitude 5.4 shallow crustal earthquake struck 243 km S of Nusa Dua, Indonesia, at a depth of 10.0 km and coordinates -10.9801°, 115.5206°. The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 44 seismic stations with good location accuracy and was assigned a USGS significance rating of 449, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 5.4 releases seismic energy equivalent to roughly 2 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 3.2 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.
