2022-12-07 08:41:31 UTC (2022-12-07) · approx. 7:41 PM UTC+11 local
On December 7, 2022 at 08:41 UTC, a magnitude 5.0 shallow crustal earthquake struck 86 km W of Sola, Vanuatu, at a depth of 39.6 km and coordinates -13.9216°, 166.7512°. This earthquake was detected by 72 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.
