Tsunami

The Hunga-Tonga Hunga-Ha'apai volcano generated the biggest atmospheric explosion recorded on Earth in more than 100 years.

NIWA is leading a New Zealand partnership to map the South and West Pacific Ocean's seabed as part of a worldwide initiative to map the entire globe’s seafloor.

A New Zealand-led team has completed the fullest investigation to date into January’s eruption of the underwater Tongan volcano.

Stacy Mohan looks at how the shockwaves from a remote Tongan island rippled through NIWA’s research community.

New findings from the record-breaking Tongan volcanic eruption are “surprising and unexpected."

The January eruption of the Tongan volcano Hunga Tonga – Hunga Ha’apai triggered tsunamis as far away as the Caribbean. NIWA scientists are onboard RV Tangaroa surveying the ocean around the volcano, working to understand the largest eruption of its kind since 1981 so they can help increase our knowledge about similar volcanoes around the world.

You’ll be blown away by what these women in science are up to onboard this RV Tangaroa voyage to the Tasman Sea.

NIWA and The Nippon Foundation are undertaking a mission to discover the undersea impacts of the recent Tongan volcanic eruption.

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.

New Zealanders and Pacific Island communities are on their way to having the most advanced tsunami monitoring system in the world.
