Powerful 7.2 magnitude earthquake strikes Vanuatu islands region in South Pacific

A major 7.2 magnitude earthquake has struck near the Vanuatu archipelago in the South Pacific Ocean, triggering immediate monitoring by regional disaster management agencies and global seismological institutes. The United States Geological Survey (USGS) as well as the Indian National Center for Seismology (NCS) registered several strong shocks in the region of South Pacific.

Rapid sequence of earthquakes strikes the coastlines of Sola and Port-Olry

Three powerful quakes occurred off the coast of Vanuatu islands in a row within hours:

Primary shock: 7.2 magnitude earthquake was registered around 200 kilometers to the west of Sola.

Secondary earthquakes: A 6.9 magnitude earthquake was registered around 197 kilometers to the west-north-west of Port-Olry; then a 6.3 magnitude earthquake was detected around 170 kilometers north-west of Port-Olry.

NCS information of the epicenter

The high-intensity earthquake was registered by NCS of India at 8:01 AM IST, having a shallow focus at 20 kilometers depth.

Sustained tectonic events in the Pacific Ring of Fire region

The series of tremors happened right after a 6.4 magnitude earthquake that occurred in the nearby Coral Sea on October 20.

The Vanuatu archipelago rests directly on the boundary of interacting tectonic plates along the Pacific Ring of Fire. This structural setup regularly produces intense deep-sea seismic activity, forcing local emergency agencies to maintain continuous tsunami and structural surveillance.
