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 ...

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 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 ...

In November 2017, Scientists from Japan, Taiwan, and USA met with our scientists to estimate the chance of a large earthquake occurring in central New Zealand (the area in the yellow box below) ...

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 ...

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) ...

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 ...

New Zealand’s tectonic setting in the Pacific puts us at risk from many different tsunami sources, some may be generated and arrive at our nearest coasts in less than an hour. To improve tsunami ...

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 ...
