On June 24, 2024 at 08:03 UTC, a magnitude 6.3 intermediate depth earthquake struck 49 km NNE of Port-Olry, Vanuatu, at a depth of 149.0 km and coordinates -14.6255°, 167.2426°. The earthquake was reported felt by 1 personacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 4.4 (moderate). The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 209 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 611, making it a moderate-impact event. The nearest populated place is Luganville (population 13,397).

Physical scale: An earthquake of magnitude 6.3 releases seismic energy equivalent to roughly 43 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 13 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 6.3 earthquakes can continue for weeks to months 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 6.3 event is significantly smaller than that historical record.
