Studying past eruptions and monitoring active volcanoes.
There are 12 active volcanic areas in New Zealand. Although the probability of an eruption affecting a large area is relatively low in any one year, New Zealand needs to be prepared for a range of styles of volcanic eruptions.
The Volcanology team at GNS Science performs a variety of scientific analyses which provide the vital information needed for thorough planning to help minimise the impact of future volcanic eruptions.
We maintain permanent surveillance at active and potentially active volcanoes - this is the best way to detect the early signs of increasing seismic and volcanic activity.
