On January 5, 2022 at 11:46 UTC, a magnitude 5.2 shallow crustal earthquake struck 85 km SW of Isangel, Vanuatu, at a depth of 10.0 km and coordinates -20.1713°, 168.8140°.

Physical scale: An earthquake of magnitude 5.2 releases seismic energy equivalent to roughly 951 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.3 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.
