2024-08-14 21:19:01 UTC (2024-08-14) · approx. 8:19 AM UTC+11 local
On August 14, 2024 at 21:19 UTC, a magnitude 4.9 shallow crustal earthquake struck 163 km SSW of Lakatoro, Vanuatu, at a depth of 10.0 km and coordinates -17.4189°, 166.7357°. This earthquake was detected by 92 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 369, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.9 releases seismic energy equivalent to roughly 338 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.4 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.
