2025-06-13 01:29:21 UTC (2025-06-13) · approx. 12:29 PM UTC+11 local
On June 13, 2025 at 01:29 UTC, a magnitude 4.9 shallow crustal earthquake struck 52 km NW of Port-Vila, Vanuatu, at a depth of 20.2 km and coordinates -17.4643°, 167.9105°. This earthquake was detected by 27 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 Vanuatu, a region characterized by the New Hebrides subduction zone, where the Australian Plate subducts eastward at approximately 90 mm per year. View all earthquakes in Vanuatu.
