The National Emergency Management Agency and GNS Science have assessed that there is no tsunami threat to New Zealand following the M8.2 Alaska Earthquake.

The National Emergency Management Agency (NEMA) is the official agency for providing tsunami advisories and warnings for New Zealand.

Based on current information, the National Emergency Management Agency (NEMA) and GNS Science have assessed that the magnitude 8.2 Alaska, United States of America earthquake is unlikely to have created a tsunami that could affect New Zealand. Coastal inundation (flooding of land areas near the shore) is not expected.

New Zealand coastal areas may experience unusual currents and unpredictable surges at the shore tomorrow (30 July 2021 NZT). Be cautious if you are at the beach or on the water.

Only messages issued by the National Emergency Management Agency represent the official warning status for New Zealand. We will provide further updates here in accordance with NEMA.

We can’t stop tsunami from happening BUT we can prepare for them. Want to know how? Here are some great places to go to get more information about New Zealand and preparing for tsunami:

Check your local tsunami zone maps via NEMA's website.

Remember, Long or Strong, Get Gone.

Long or strong get run

Drop, Cover and Hold during the shaking. Protect yourself from the earthquake first.

As soon as the shaking stops, move immediately to the nearest high ground, out of all tsunami evacuation zones, or as far inland as possible.

The National Emergency Management Agency (NEMA) have a great website with information on what to do before, during and after a tsunami. There you can also find tsunami evacuation zone maps for around New Zealand, and what supplies you need in an emergency.
