Earthquakes

The Tangaroa assisted in New Zealand’s largest ever deployment of seafloor earthquake recording instruments in a bid to learn more about the earthquake behaviour of the tectonic plates beneath the east coast of the North Island.
It is well known that earthquakes can trigger tsunami but they can also be caused by landslides – with devastating effects.
Since the end of June, a barge has been stationed just off Wellington’s Miramar Peninsula drilling into the seabed to find an alternative water source for the city.
NIWA scientists have found signs of recovery in the Kaikōura Canyon seabed, 10 months after powerful submarine landslides triggered by the November earthquake wiped out organisms living in and on the seabed.
NIWA vessel RV Tangaroa visted Kaikōura in September 2017 to investigate the impacts of the earthquake in the coastal zone, which includes effects on rocky reef habitats and communities, pāua fishery and Hector’s dolphins.
Imagine if you could foresee what would happen to your home in a severe flood or tsunami, and then work out how to prevent or reduce the impact before any such event occurred.

The sounds of whales and dolphins rarely seen in New Zealand waters have been recorded by a NIWA scientist in a pioneering underwater sound project.

Recording underwater biodiversity after earthquakes

NIWA’s marine ecologist Dr Dave Bowden talks about the catastrophic changes to the seafloor in the Kaikoura Canyon following the November 2016 earthquake.

Earthquake's unseen impact

NIWA scientists on board RV Ikatere have been surveying the coastal area around Kaikoura for the first time since November's magnitude 7.8 earthquake in 2016. Their work has revealed significant changes to the sea floor...

Huge mudslides from November’s earthquakes have wiped out all organisms living in the seabed of the Kaikōura Canyon.

NIWA’s flagship research vessel Tangaroa has been diverted to survey the seabed in areas affected by Monday’s earthquake.

Seismic research by NIWA scientists off the West Coast of the South Island has identified faults capable of causing earthquakes with magnitudes of up to 7.8.

The Ocean Survey 20/20 (OS 20/20) programme is a Government initiative, which aims to provide New Zealand with better knowledge of its ocean territory, including New Zealand's Exclusive Economic Zone (EEZ), Continental Shelf and the Ross Sea Region.

Scientists have been working on ways to find out about earthquakes that occurred before oral and written records
began in New Zealand.

In September 2010 and February 2011, two devastating earthquakes (M7.1 and M6.3 respectively) hit the Canterbury region

Welcome to this special edition of  Natural Hazards Update, highlighting the Shallow Survey 2012.

Welcome to NIWA's third Alumni Update – an e-newsletter for past NIWA employees.

Welcome to NIWA's second Alumni Update – an e-newsletter for past NIWA employees.

NIWA scientists are working at the cutting edge of earthquake research, developing new ways to interpret the history of undersea earthquakes occurring on major faultlines around New Zealand. This work will help scientists determine the likelihood of damaging earthquakes from underwater faults close to the coast.

Three new posters of the Cook Strait and Wellington Harbour seabed reveal for the first time a treasure trove of detailed information for the benefit of all New Zealanders.

14 September 2009 - Port of New Orleans CEO, Gary La Grange, is in Wellington to talk about the lessons New Orleans learnt from its recovery from Hurricane Katrina and how these experiences can help protect coastal and port areas worldwide. Mr La Grange is one of the keynote speakers at the Australasian Coasts and Ports Conference at Te Papa Tongarewa, from 16-18 September 2009.
