Tauranga Volcanic Centre

Tauranga Volcanic Centre
Map
Map of selected surface volcanic features of the Tauranga Volcanic Centre alone (see other map on this page for volcanic relationships). Much of the centre to the south is buried under the Mamaku ignimbrite from the Rotorua Caldera which may extend even to Matakana Island in Tauranga Harbour. There is one basaltic centre (gray) on the island. The buried approximate outline of the postulated Omanawa Caldera which likely contributed to Centre ignimbrites is in pale white towards present Lake Rotorua. Brown shows the Waiteariki Ignimbrite. If you click on the map you will enable mouseover of volcano feature/wikilink. Characterised vents are black rectangles. Rhyolite fields from known vents is in red (geologically typed as Minden rhyolite) and andesite from the Otawa Formation is pink. Purple is Papamoa Ignimbrites.[1][2][3][4]

The Tauranga Volcanic Centre is a geologic region in New Zealand's Bay of Plenty. It extends from the southern end of Waihi Beach and from the old volcanoes of the Coromandel Peninsula that make up the northern part of the Kaimai Range, towards the Taupō Volcanic Zone.

It was the site, about 2.1 million years ago, of the large single eruption event of Waiteariki ignimbrite with DRE of 870 ± 87 km3 (209 ± 21 cu mi).[5]: 73
