Formed about 220,000 years ago, Rotorua caldera is today a lake next to one of New Zealand's major tourist destinations.
The 22 km wide Rotorua caldera is the northwestern-most caldera of the Taupō Volcanic Zone; it is also the only single-event caldera. The city of Rotorua lies close to the active geothermal fields of Tikitere and Whakarewarewa.
