how are volcanoes monitored in New Zealand- Research

 GNS Science study extinct and active volcanoes in New Zealand to better understand what is happening in the dynamic landscape. The research has applications in volcanology, preparedness, emergency response and community resilience

researchers:

Use radioactive isotopes to date eruptions

Link rocks to past eruptions to see how far material travelled

Conduct geochemical analyses of material expelled to understand the state of the magma system driving the volcano when it erupted

Examine the material from a particular site for clues to the duration, magnitude and length of each phase of an eruption

Also monitor present conditions of New Zealand’s active volcanoes by:

Visual observations

Chemical analyses

Seismic and acoustic monitoring

Ground deformation assessments

Data from monitoring of volcanoes is fed into GeoNet. The volcano monitoring team gauge the present state of our active volcanoes and communicate this through the NZ Volcanic Alert Level system and through direct communication with stakeholders, responding agencies, infrastructure providers and the public.
