2024-08-22 20:33:52 UTC (2024-08-22) · approx. 7:33 AM UTC+11 local
On August 22, 2024 at 20:33 UTC, a magnitude 4.7 intermediate depth earthquake struck 50 km N of Isangel, Vanuatu, at a depth of 221.1 km and coordinates -19.0853°, 169.2946°. This earthquake was detected by 63 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 340, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.7 releases seismic energy equivalent to roughly 169 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.1 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.
