2024-12-19 18:36:13 UTC (2024-12-19) · approx. 5:36 AM UTC+11 local
On December 19, 2024 at 18:36 UTC, a magnitude 5.1 shallow crustal earthquake struck 103 km SW of Isangel, Vanuatu, at a depth of 10.0 km and coordinates -20.1481°, 168.5242°. This earthquake was detected by 54 seismic stations with good location accuracy and was assigned a USGS significance rating of 400, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.1 releases seismic energy equivalent to roughly 674 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.0 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.
