Hazards: Eruptions, Earthquakes and Tsunamis

A big question we are trying to answer is: What happens when a volcano erupts in Auckland? To answer this we are studying the timing, size, location, and deposits of past eruptions to look for patterns, and to identify the threats to Auckland from future eruptions. We are also interested in related hazards, such as earthquakes, tsunami and fire.

New Research: Scientists examine evacuation timelines for future Auckland volcanic eruptions

DEVORA scientists are working to understand how long it might take for people to move out of harm’s way ahead of a future eruption of the Auckland Volcanic Field. Check out this new research lead by DEVORA PhD Candidate Alec Wild to find out how long it would take !
