National Advisory: Tsunami activity – expect strong and unusual currents and unpredictable surges at the shore

The Team from Neighbourly.co.nz

New Zealand may experience strong and unusual currents and unpredictable surges at the shore following a magnitude 8.7 earthquake off the East Coast of Russia at 2025-07-30 11:25 AM.

Strong currents and surges can injure and drown people. There is a danger to swimmers, surfers, people fishing, and anyone in or near the water close to shore.

People in or near the sea in the following areas should move out of the water, off beaches and shore areas and away from harbours, marinas, rivers and estuaries.

AREAS UNDER THREAT:
ALL COASTAL AREAS OF THE NORTH ISLAND, GREAT BARRIER ISLAND, THE SOUTH ISLAND, STEWART ISLAND, and the CHATHAM ISLANDS (updated: 3.02pm, 30/07/2025)

ADVICE FOR PEOPLE IN AREAS UNDER THREAT:
STAY OFF THE BEACHES AND SHORE AREAS

People on boats, live-aboards and at marinas should leave their boats/vessels and move onto shore. Do not return to boats unless instructed by officials.

There is no need to evacuate other areas unless directly advised by local civil defence authorities. Coastal inundation (flooding of land areas near the shore) is not expected as a result of this event. We are advising people to:
- Move out of the water, off beaches and shore areas and away from harbours, marinas, rivers and estuaries.
- Do not go to the coast to watch the unusual wave activity as there may be dangerous and unpredictable surges.
- Listen to local civil defence authorities and follow any instructions.
- Share this information with family, neighbours and friends.
- Strong and unusual currents and unpredictable surges will continue for several hours and the threat must be regarded as real until the Civil Defence states otherwise.

The situation may change as new information becomes available. Listen to the radio or TV for updates, or check www.civildefence.govt.nz...
