On April 11, 2024 at 16:08 UTC, a magnitude 4.8 intermediate depth earthquake struck 39 km ESE of Port-Olry, Vanuatu, at a depth of 130.1 km and coordinates -15.2306°, 167.3796°. This earthquake was detected by 54 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 355, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 4.8 releases seismic energy equivalent to roughly 239 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.2 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.
