Hazards

University of Canterbury’s Professor Matthew Wilson, one of the Mā te haumaru ō te wai research team, gives us some insight on uncertainty.

New Zealand’s weather is proving no exception to the record-breaking extremes occurring around the globe.

The Tongan volcanic eruption may be responsible for New Zealand’s unusually vibrant sunrises and sunsets, say NIWA scientists.

Climate change means more intense storm systems are on their way. Science can’t stop it raining, but it can help communities prepare for the worst and plan for the future.

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."

A weekly update describing soil moisture patterns across the country to show where dry to extremely dry conditions are occurring or imminent.

Our team onboard RV Tangaroa are equipped with all the tech and tools they need to explore the undersea changes caused by the devastating volcanic eruption in Tonga earlier this year.

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.

Samples are collected to understand how the seafloor geology, biogeochemistry and ecosystem health has been affected by the volcanic eruption.
