M5.6 Earthquake 190 km NE of Sola, Vanuatu — January 23, 2025
2025-01-23 11:14:02 UTC (2025-01-23) · approx. 10:14 PM UTC+11 local
On January 23, 2025 at 11:14 UTC, a magnitude 5.6 deep-focus earthquake struck 190 km NE of Sola, Vanuatu, at a depth of 598.0 km and coordinates -12.7706°, 168.8952°. The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 125 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 482, placing it among routine seismic activity. The nearest populated place is Sola (population 1,171).
Physical scale: An earthquake of magnitude 5.6 releases seismic energy equivalent to roughly 4 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 4.4 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.
