Details for: Auckland Volcanic Field

The 140 km2 Auckland Volcanic Field is overlain by New Zealand's largest city. This view looking SW from the summit of Rangitoto volcano shows volcanic cones on a peninsula extending into Waitemata Harbor with downtown Auckland behind it. North Head (left) and Mount Victoria (right) on the peninsula are two of the more than 50 maars, tuff rings, and scoria cones that have formed in the past 150,000 years. Rangitoto is the only known Holocene volcano. Photo by Ichio Moriya (Kanazawa University).
