Auckland Volcanic Field

Our History

For more than 10 years, DEVORA (DEtermining VOlcanic Risk in Auckland) has been focused on preparing New Zealand’s largest city for a volcanic eruption – and the ongoing disruption.

Matching volcanic ash to its source

The collation of whole-rock major and trace element data has led to the development of a method to correlate volcanic ash samples to their source volcanic centres.

Downhole seismometers lead to a refined velocity model

By refining the velocity model used to locate earthquakes, Auckland can be better prepared for an eruption from the volcanic field that lies beneath the region in New Zealand’s upper North Island.

Multiple melting points suggest erratic eruptions worldwide

Discrete melt batches that move at different depths and speeds may explain the erratic spatial and temporal pattern of eruptions in the Auckland Volcanic Field (AVF).

Role-play puts worst-case scenario in volcanic hazard spotlight

Volcanic crisis simulation and role-play are valuable tools in communicating hazard assessment, learning monitoring and emergency management skills, as well as developing teamwork and decision-making strengths.
