New research reveals more than 320,000 Aucklanders would need to evacuate the supercity in the event of a volcanic eruption. It would take more than two days for everyone to get safely away, Stuff reports. The research also found that, while there are 53 known volcanoes in Auckland, eruptions in the region are generally smaller than those in the central North Island, and happen in a new location each time. The study – Modelling spatial population exposure and evacuation clearance time for the Auckland Volcanic Field, New Zealand – was published in the Journal of Volcanology and Geothermal Research.
