2024-07-22 14:38:19 UTC (2024-07-22) · approx. 1:38 AM UTC+11 local
On July 22, 2024 at 14:38 UTC, a magnitude 5.0 shallow crustal earthquake struck 99 km ENE of Norsup, Vanuatu, at a depth of 10.7 km and coordinates -15.5975°, 168.1951°. This earthquake was detected by 56 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.
