2025-03-28 01:53:55 UTC (2025-03-28) · approx. 12:53 PM UTC+11 local
On March 28, 2025 at 01:53 UTC, a magnitude 5.0 intermediate depth earthquake struck 79 km ENE of Lakatoro, Vanuatu, at a depth of 167.6 km and coordinates -15.9497°, 168.1390°. This earthquake was detected by 63 seismic stations with good location accuracy and was assigned a USGS significance rating of 385, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.0 releases seismic energy equivalent to roughly 477 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.7 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.
