Shallow M5.8 earthquake hits Kermadec Islands, New Zealand

A shallow M5.8 earthquake was recorded in the Kermadec Islands, New Zealand, at 09:02 UTC on August 30, 2026. The earthquake occurred at a depth of 35.0 km (21.7 miles), as reported by the USGS.

The coordinates for this event are -30.1°S, 177.9°W, situating it in the Kermadec Islands, a remote volcanic island chain northeast of New Zealand’s North Island. The area is uninhabited, and the nearest populations are hundreds of kilometers to the southwest.

Given the remote, oceanic location of the Kermadec Islands, there are no major population centers or significant critical infrastructure such as airports, ports, or highways in the immediate vicinity.

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

USGS issued a green alert for this event, indicating a low likelihood of casualties or damage. The maximum estimated intensity was IV on the Modified Mercalli scale. The significance index is 518 (on a scale that runs through 1 000), based on magnitude, felt reports, and estimated impact.

The Kermadec Islands region lies along the boundary between the Pacific and Australian tectonic plates. This subduction zone is known for frequent and sometimes powerful seismic activity.
