New study reveals Auckland’s volcanic hazard zones

The susceptibility map of Auckland. Red and orange shows areas that have a higher risk of explosive volcanic activity. Courtesy:  MasseyNew Zealand: A new study has found Three Kings and Mangere are the most susceptible suburbs in Auckland to a volcanic eruption. Gábor Kereszturi, a PhD student from Massey University, used a GIS mapping technique to give areas a susceptiblity score in the event of an eruption. Gábor Kereszturi, a PhD student from Massey University’s Institute of Agriculture and Environment, used GIS-based mapping technique to volcanology to understand potential volcanic hazards of the broader Auckland region. He used it to study the Auckland Volcanic Field, a 360kmsq area stretching from the North Shore to the Manukau lowlands.

Kereszturi collected information from a detailed map of the topography of the field created from a laser scanner mounted on a low-flying helicopter. The second layer combined topographic data with geological maps and field mapping, helping him understand how past volcanoes erupted and indentify which areas they affected.
