Rangitoto Island

Rangitoto Island is a volcanic island in the Hauraki Gulf near Auckland, New Zealand. The 5.5 km wide island is an iconic and widely visible landmark of Auckland with its distinctive symmetrical shield volcano cone rising 260 metres (850 ft) high over the Hauraki Gulf. Rangitoto is the most recent and the largest (2311 hectares) of the approximately 50 volcanoes of the Auckland volcanic field.
It was formed by a series of eruptions between 550 and 600 years ago. The eruptions occurred in two episodes, 10–50 years apart, and are thought to have lasted for several years during the later shield-forming episode. The first episode erupted most of the volcanic ash that mantles Motutapu Island next door, and produced the lower, northern, scoria cone. The second episode built most of Rangitoto erupting all the lava flows and main scoria cone at the apex. The 2.3 cubic kilometres of material that erupted from the volcano was about equal to the combined mass-produced by all the previous eruptions in the Auckland volcanic field, which were spread over more than 250,000 years.
