M6.2 Earthquake 82 km W of Port-Vila, Vanuatu — February 16, 2021
2021-02-16 00:49:25 UTC (2021-02-16) · approx. 11:49 AM UTC+11 local
Felt by 86 people across nearby locations. Maximum shaking intensity MMI 4.8 (moderate).
On February 16, 2021 at 00:49 UTC, a magnitude 6.2 shallow crustal earthquake struck 82 km W of Port-Vila, Vanuatu, at a depth of 13.0 km and coordinates -17.8292°, 167.5413°. The earthquake was reported felt by 86 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 4.8 (moderate). The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. The nearest populated place is Lakatoro (population 705).
Physical scale: An earthquake of magnitude 6.2 releases seismic energy equivalent to roughly 30 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 11 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 6.2 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 6.2 event is significantly smaller than that historical record.
