2026-05-19 02:29:24 UTC (1 day ago) · approx. 1:29 PM UTC+11 local
Felt by 12 people across nearby locations. Maximum shaking intensity MMI 4.0 (moderate).
On May 19, 2026 at 02:29 UTC, a magnitude 5.7 shallow crustal earthquake struck 51 km SSW of Port-Vila, Vanuatu, at a depth of 27.0 km and coordinates -18.1511°, 168.0931°. The earthquake was reported felt by 12 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 4.0 (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 127 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 504, placing it among routine seismic activity. The nearest populated place is Pango (population 2,485).
Physical scale: An earthquake of magnitude 5.7 releases seismic energy equivalent to roughly 5 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 5.2 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.

Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 5.7 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 5.7 event is significantly smaller than that historical record.
What should I do after an earthquake?
If you were in the affected area: check yourself and others for injuries, inspect your home for damage, and be prepared for aftershocks. For detailed guidance, see our earthquake safety guide and emergency planning resources.
