On July 1, 2020 at 14:58 UTC, a magnitude 4.8 shallow crustal earthquake struck 59 km SW of Lakatoro, Vanuatu, at a depth of 10.0 km and coordinates -16.4750°, 167.0157°.

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.
