How long will it take for potential tsunami waves to reach New Zealand?

Question

Accepted Answer

Potential tsunami waves could reach New Zealand in at least two hours

New Zealand's civil defence organisation is monitoring the situation following a 7.4 magnitude earthquake near the Kermadec islands. If a tsunami is generated by this seismic event, it is estimated that it would take at least two hours to reach the country. The Pacific Tsunami Warning Center has indicated that hazardous tsunami waves are a possibility within a 300 km radius of the earthquake's epicentre, specifically along the coasts of the Kermadec islands.
Monitoring of the situation is underway

Authorities in New Zealand have stated that they are actively monitoring the developments following the earthquake. This monitoring process is crucial for assessing any potential threats, including the generation and trajectory of tsunami waves. The civil defence organisation is prepared to provide updates as the situation evolves.
Tsunami wave travel time estimated at over two hours

The preliminary assessment by New Zealand's civil defence indicates a minimum travel time of two hours for any potential tsunami waves to reach the country's shores. This timeframe allows for a period of assessment and preparation for coastal communities. The earthquake's location, approximately 928 kilometres northeast of Tauranga, influences this estimated arrival time.
Hazardous waves possible near the epicentre

The Pacific Tsunami Warning Center has identified a specific risk zone for hazardous tsunami waves. This zone is defined as being within 300 km of the earthquake's epicentre, with particular concern for the coastlines of the Kermadec islands. The earthquake itself occurred at a depth of 34 km.
