2025-01-16 13:27:32 UTC (2025-01-16) · approx. 12:27 AM UTC+11 local
On January 16, 2025 at 13:27 UTC, a magnitude 5.0 shallow crustal earthquake struck 147 km S of Isangel, Vanuatu, at a depth of 28.7 km and coordinates -20.8697°, 169.2452°. This earthquake was detected by 61 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 385, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.0 releases seismic energy equivalent to roughly 477 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.7 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.
