M4.8 Earthquake 13 km SSW of Port-Vila, Vanuatu — May 19, 2026
2026-05-19 14:18:39 UTC (1 day ago) · approx. 1:18 AM UTC+11 local
Felt by 8 people across nearby locations. Aftershock of the M5.7 mainshock.
On May 19, 2026 at 14:18 UTC, a magnitude 4.8 shallow crustal earthquake struck 13 km SSW of Port-Vila, Vanuatu, at a depth of 62.1 km and coordinates -17.8472°, 168.2588°. This earthquake was detected by 79 seismic stations with good location accuracy and was assigned a USGS significance rating of 357, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.8 releases seismic energy equivalent to roughly 239 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.2 km — a useful intuition for the size of the slip patch on the fault.
This earthquake is part of an ongoing aftershock sequence following the magnitude 5.7 mainshock that occurred 1 day ago 51 km SSW of Port-Vila, Vanuatu. Since the mainshock, the USGS has recorded 0 aftershocks in this area. Aftershock activity is expected to continue for days to weeks as stresses on surrounding faults redistribute.
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.

Common Questions
How strong was the magnitude 4.8 earthquake near Port-Vila, Vanuatu?
The magnitude 4.8 earthquake that struck 13 km SSW of Port-Vila, Vanuatu on May 19, 2026 at 14:18 UTC had a depth of 62.1 km. For context, this was a light earthquake commonly felt near the epicenter.
Where did the earthquake occur?
The earthquake epicenter was located at -17.8472°, 168.2588°, which is 13 km SSW of Port-Vila, Vanuatu. View all earthquakes in Vanuatu.
Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 4.8 earthquakes can continue for several days and gradually diminish over time.
Is this the same earthquake as the M5.7 one earlier?
No. This magnitude 4.8 earthquake is an aftershock of the larger magnitude 5.7 mainshock that occurred earlier 51 km SSW of Port-Vila, Vanuatu. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.
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 4.8 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.
