M5.8 Earthquake 101 km ENE of Luganville, Vanuatu — September 11, 2024
2024-09-11 19:22:55 UTC (2024-09-11) · approx. 6:22 AM UTC+11 local
Maximum shaking intensity MMI 6.0 (very strong).
On September 11, 2024 at 19:22 UTC, a magnitude 5.8 shallow crustal earthquake struck 101 km ENE of Luganville, Vanuatu, at a depth of 18.8 km and coordinates -15.2570°, 168.0658°. The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 114 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 518, placing it among routine seismic activity. The nearest populated place is Saratamata (population 0).
Physical scale: An earthquake of magnitude 5.8 releases seismic energy equivalent to roughly 8 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 6.1 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.

Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 5.8 earthquakes can continue for days to weeks and gradually diminish over time.
Has Vanuatu had earthquakes this big before?
The largest recorded earthquake in Vanuatu was the M7.9 Vanuatu earthquake of October 7, 2009. Today's magnitude 5.8 event is significantly smaller than that historical record.
