A volcanic eruption in Auckland will likely result in slow moving rivers of lava flowing through densely populated areas, which is why our scientists are looking to La Palma for lessons from its 2021 ...

Whakaari/White Island is currently passively emitting a weak-to-moderate steam and gas plume that contains minor volcanic ash. The Volcanic Alert Level remains at Level 2 and the Aviation Colour Code ...

The timestamp shown at the top right of the images is the time when the images were last refreshed. The previous 36 hours of sea level variations from all operational sites are displayed, oldest to ...

The timestamp shown at the top right of the seismograph drum shown above is the time when this image was last refreshed. The previous four hours (240 minutes) of seismic signals (also known as traces) ...

Felt earthquake reports are quantified using the New Zealand Modified Mercalli (MM) intensity scale. The MM scale grades the impact of an earthquake on people living on the earth's surface, and so can ...

Monitoring active volcanoes requires the use of several complementary techniques to ‘take the pulse of a volcano’. Collectively, this is known as volcano monitoring. The techniques we use to monitor ...

One hazard we don’t often get an opportunity to talk about at GeoNet is landslides. That’s a good thing, we aren’t complaining. But with the M7.8 Kaikōura Earthquake, landslides and land deformation ...

The size of an earthquake is often described using magnitude, which is the amount of energy released during an earthquake. However, not all of the energy released in an earthquake will necessarily be ...

An interactive, multi-layered map displaying the peak strong motion data that GeoNet collected during the last hour. Select a site to view the PGA (g), PGV (cm/s) and MMI values. Sites are coloured to ...

The Aviation Colour Code system is based on four colours and is only intended for use by the civil aviation community. The system is defined by the International Civil Aviation Organization(ICAO), and ...

New Zealanders live on the edge. Depending on their location, it might be the edge of the Australian Plate or it might be the edge of the Pacific Plate. The active Pacific-Australian Plate boundary ...

If we have helped you, please acknowledge us! All data and images are made available free of charge through the GeoNet programme to facilitate research into hazards and assessment of risk. Users are ...
