On May 30, 2025 at 04:01 UTC, a magnitude 4.6 intermediate depth earthquake struck 49 km S of Sola, Vanuatu, at a depth of 197.5 km and coordinates -14.3189°, 167.4683°. This earthquake was detected by 29 seismic stations with good location accuracy and was assigned a USGS significance rating of 326, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 4.6 releases seismic energy equivalent to roughly 120 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 899 m — 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 5.1 mainshock that occurred 17 days ago 59 km NNE of Port-Olry, Vanuatu. Since the mainshock, the USGS has recorded 1 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 4.6 earthquake near Sola, Vanuatu?

The magnitude 4.6 earthquake that struck 49 km S of Sola, Vanuatu on May 30, 2025 at 04:01 UTC had a depth of 197.5 km. For context, this was a light earthquake commonly felt near the epicenter.

Where did the earthquake occur?

The earthquake epicenter was located at -14.3189°, 167.4683°, which is 49 km S of Sola, Vanuatu. View all earthquakes in Vanuatu.

Were there aftershocks?

Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 4.6 earthquakes can continue for several days and gradually diminish over time.

Is this the same earthquake as the M5.1 one earlier?

No. This magnitude 4.6 earthquake is an aftershock of the larger magnitude 5.1 mainshock that occurred earlier 59 km NNE of Port-Olry, 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 4.6 event is significantly smaller than that historical record.
