On October 17, 2024 at 02:18 UTC, a magnitude 4.9 intermediate depth earthquake struck 60 km E of Port-Olry, Vanuatu, at a depth of 107.2 km and coordinates -14.9629°, 167.6304°. This earthquake was detected by 38 seismic stations with moderate location accuracy and was assigned a USGS significance rating of 370, 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.
