Earthquake activity in Coral Sea

A strong magnitude 5.0 earthquake struck the Coral Sea 126 km southwest of Tegua Island in Torba Province, Vanuatu, on Saturday evening at 10:31 pm local time (per VolcanoDiscovery).

This latest quake follows several earlier tremors including a 4.8-magnitude event on Saturday morning and a 4.6-magnitude temblor on Friday, all centered near Tegua Island, according to VolcanoDiscovery reports.

The region remains seismically active with multiple quakes reported in recent days; residents are being monitored for potential aftershocks or tsunami risks, per local emergency services.

Vanuatu's government has been working with the United Nations to implement an Anticipatory Action Framework for Tropical Cyclones, which may help prepare for any weather-related impacts from these seismic events.
