M5.0 Earthquake 67 km N of Isangel, Vanuatu — December 25, 2021
2021-12-25 12:19:57 UTC (2021-12-25) · approx. 11:19 PM UTC+11 local
On December 25, 2021 at 12:19 UTC, a magnitude 5.0 intermediate depth earthquake struck 67 km N of Isangel, Vanuatu, at a depth of 226.0 km and coordinates -18.9362°, 169.2459°.
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.
