New maps from NIWA and the Deep South National Science Challenge show areas across Aotearoa New Zealand that could be inundated by extreme coastal flooding.

Beachgoers could be safer thanks to a new technology with the potential to give real-time updates of rip currents.

Prior to 15 January, Hunga Tonga-Hunga Ha'apai was a little-known undersea South Pacific volcano with a long name. Within 24 hours, it  was a global phenomenon – the site of the largest atmospheric explosion in almost 150 years. Jessica Rowley looks at why a remote Tongan volcano took the world by storm.

NIWA and Surf Life Saving New Zealand are working together to develop a state-of-the-art, rip current identification tool underpinned by artificial intelligence (AI) and deep learning technologies.

Marsden-funded research investigating how erupting volcanoes can cause deadly and damaging tsunamis.

Innovative experiments are giving natural hazard researchers and PhD students a close look at how erupting volcanoes can cause deadly and damaging tsunamis.

We combine capabilities in weather, wave, storm surge and tide forecasting with tide gauge observations.

Researchers have recovered a scientific buoy from the Kāpiti Marine Reserve that went missing in late March.

A network of state-of-the-art tsunami buoys is being deployed from New Zealand up into the Pacific to keep communities safer.

NIWA scientists have completed the first national assessment of people and buildings at risk in New Zealand’s tsunami evacuation zones.

High waves pounding Wellington’s south coast today are being caused by a deep area of low pressure passing the Chatham Islands, according to NIWA forecaster Ben Noll.

New Zealand’s changing ocean environment has prompted the call to develop a system that will keep closer tabs on information from scientific monitoring buoys so the data they produce can be shared as widely as possible.
