		The Rotorua Lake and low lying basin area is part of the Rotorua Caldera, which dates back 140,000 years when major volcanic eruptions formed the Mamaku Plateau of ignimbrite deposits.
		The Caldera resulted from magma (molten rock) erupting through vents from underground and depositing the erupted material (the ignimbrite) on the surrounding countryside.
		Using a map of Rotorua, places, buildings, schools, industrial areas, commercial areas, recreation areas, the road network can be discussed and plotted.

		Rotorua is the only single-event caldera in the Taupo volcanic zone and was formed about 220,000 years ago following eruption of the >340 cu km rhyolitic Mamaku Ignimbrite.
		Although caldera collapse occurred in a single event, the process was complex and involved multiple collapse blocks.
		The major thermal areas of Takeke, Tikitere, Lake Rotokawa, and Rotorua-Whakarewarewa are located within the caldera or outside its rim, and the city of Rotorua lies within and adjacent to active geothermal fields.

	Lakes - Tarawera
		Lake Rotorua is situated in a caldera (inverted volcano which has collapsed into itself) which was created approximately 140,000 years ago during an ignimbrite eruption.
		The result was the Rotorua caldera, which filled by rainwater and surrounding lakes became Lake Rotorua (the lake was 80m above the current level!).
		The Predominant species of fish found in Rotorua are Rainbow and Brown trout, and small amounts of Brook Trout in places.

		Caldera formation generally follows the climax of major volcanic activity.
		Portions of the magma still trapped beneath the caldera may then be erupted on the floor or along the walls of the caldera.
		The caldera may fill with water forming a lake and the new lava domes can typically form islands as in Lake Taupo and Lake Rotorua.

	FIRE AND WATER: LATE QUATERNARY MEGAFLOODS IN THE TAUPO VOLCANIC ZONE, NEW ZEALAND
		The Taupo Volcanic Zone in the central North Island of New Zealand is an area of intense Quaternary silicic volcanism, characterized by frequent caldera-forming explosive eruptions from multiple short-lived, nested, and/or overlapping volcanic centers.
		Both of the largest caldera lakes, Taupo and Rotorua, are fringed by extensive terrace and shoreline deposits laid down in the aftermath of explosive rhyolitic eruptions that provide evidence for prolonged highstand periods followed by sudden falls in lake level, that, in some cases, are linked to catastrophic outbreak floods.
		The Rotorua caldera, formed at 220 ka during eruption of the Mamaku Ignimbrite, contains both post-Mamaku lake sediments and extensive highstand terraces developed after eruption of the Rotoiti Breccia from the adjacent Okataina caldera at 64 ka again blocked the outlet.
