2023-07-26 23:13:08 UTC (2023-07-26) · approx. 10:13 AM UTC+11 local
On July 26, 2023 at 23:13 UTC, a magnitude 5.1 shallow crustal earthquake struck 82 km SSE of Sola, Vanuatu, at a depth of 11.9 km and coordinates -14.5494°, 167.8834°. This earthquake was detected by 104 seismic stations with good location accuracy and was assigned a USGS significance rating of 400, placing it among routine seismic activity.
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.
