M5.1 earthquake – south of the Fiji Islands, Fiji

An M5.1 earthquake was recorded at 06:27 UTC on June 22, 2025, south of the Fiji Islands. The seismic event occurred at a depth of 10.0 km (6.2 miles), based on data from the USGS. The coordinates of the epicenter were -26.4°S, 177.3°W, placing the quake in the open waters south of Fiji.

This offshore earthquake was located well south of the Fiji archipelago, with no major islands or densely populated centers in the immediate vicinity of the epicenter. The region features sparsely populated island groups and vast stretches of ocean.

Given the offshore nature of the event, critical infrastructure such as major ports, airports, or highways are not expected to be directly affected. The area is primarily maritime with limited infrastructure exposure.

There is no tsunami threat associated with this earthquake, based on its location and available data.

The significance index is 400 (on a scale that runs through 1 000), based on magnitude, felt reports, and estimated impact.

The Fiji region lies along the tectonically active Pacific “Ring of Fire,” where the Pacific Plate interacts with the Indo-Australian Plate, resulting in frequent seismic activity.
