M5.1 Earthquake 53 km NW of Port-Vila, Vanuatu — June 4, 2020
2020-06-04 11:21:53 UTC (2020-06-04) · approx. 10:21 PM UTC+11 local
On June 4, 2020 at 11:21 UTC, a magnitude 5.1 shallow crustal earthquake struck 53 km NW of Port-Vila, Vanuatu, at a depth of 35.0 km and coordinates -17.4436°, 167.9099°.
Physical scale: An earthquake of magnitude 5.1 releases seismic energy equivalent to roughly 674 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.0 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.
