2021-06-09 20:41:59 UTC (2021-06-09) · approx. 7:41 AM UTC+11 local
On June 9, 2021 at 20:41 UTC, a magnitude 4.5 shallow crustal earthquake struck 44 km SW of Sola, Vanuatu, at a depth of 26.4 km and coordinates -14.1820°, 167.2835°.
Physical scale: An earthquake of magnitude 4.5 releases seismic energy equivalent to roughly 85 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 767 m — 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.
