2025-03-10 04:50:56 UTC (2025-03-10) · approx. 3:50 PM UTC+11 local
On March 10, 2025 at 04:50 UTC, a magnitude 4.8 intermediate depth earthquake struck 33 km ENE of Luganville, Vanuatu, at a depth of 117.0 km and coordinates -15.4378°, 167.4611°. This earthquake was detected by 54 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 354, placing it among routine seismic activity.
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.
