Hazards

NIWA researchers study geological, weather and coastal hazards, including the impact of climate change on some of these.

  • Know your snow

    Feature story
    With the winter snowpack starting to build, who’s keeping an eye out on conditions in the mountains?
  • The largest flood flow ever measured

    Media release
    Flood flows on the Buller River this month were the largest of any river in Aotearoa New Zealand in almost 100 years, NIWA measurements show.
  • Tsunami generated by underwater volcanoes

    Research Project
    Marsden-funded research investigating how erupting volcanoes can cause deadly and damaging tsunamis.
  • Explosive research sheds light on volcanic tsunami

    Feature story
    Innovative experiments are giving natural hazard researchers and PhD students a close look at how erupting volcanoes can cause deadly and damaging tsunamis.
  • NIWA calculates 1:200 year flood for parts of Canterbury

    Media release
    Preliminary analysis by NIWA climate scientists has shown that the recent Canterbury rainfall was so extreme in some inland places that it could be expected to happen only once every 200 years.
  • Field teams and forecasters cover monumental rainfall event

    Feature story
    The prodigious rainmaker that hit Canterbury earlier this month saw NIWA field teams out in the elements collecting flood data from bridges, cableways and jetboat gaugings.
  • Storm surge and wave forecasting

    Service
    We combine capabilities in weather, wave, storm surge and tide forecasting with tide gauge observations.
  • Scientists examine high winds on Auckland Harbour Bridge

    Media release
    When high winds on the Auckland Harbour Bridge last September caused two trucks to topple over, one into a load-bearing strut, NIWA scientists began thinking about what role they could play in preventing it from happening again.
  • 2021 - Hikurangi margin

    Voyage
    Underwater Remotely Operated Vehicle helping scientists collect the latest earthquake data.
  • Hotspot Watch 12 March 2021

    Hotspot
    A weekly update describing soil moisture patterns across the country to show where dry to extremely dry conditions are occurring or imminent. Regions experiencing significant soil moisture deficits are deemed “hotspots”. Persistent hotspot regions have the potential to develop into drought.
