The Taupō Volcanic Zone (TVZ) is a volcanic area in the North Island of New Zealand that has been active for the past two million years and is still highly active. Mount Ruapehu marks its south-western end and the zone runs north-eastward through the Taupō and Rotorua areas and offshore into the Bay of Plenty. It is part of the larger Central Volcanic Region that extends further westward through the western Bay of Plenty to the eastern side of the Coromandel Peninsula and has been active for four million years. At Taupō the rift volcanic zone is widening east–west at the rate of about 8 mm per year while at Mount Ruapehu it is only 2–4 mm per year but this increases at the north eastern end at the Bay of Plenty coast to 10–15 mm per year. It is named after Lake Taupō, the flooded caldera of the largest volcano in the zone, the Taupō Volcano and contains a large central volcanic plateau as well as other landforms associated with its containing tectonic intra-arc continental Taupō Rift.
The Pink and White Terraces, were natural wonders of New Zealand. They were reportedly the largest silica sinter deposits on earth. Until recently, they were lost and thought destroyed in the 1886 eruption of Mount Tarawera, while new hydrothermal features formed to the south-west i.e. Waimangu Volcanic Rift Valley.
Mount Tarawera is a volcano on the North Island of New Zealand within the older but volcanically productive Ōkataina Caldera. Located 24 kilometres southeast of Rotorua, it consists of a series of rhyolitic lava domes that were fissured down the middle by an explosive basaltic eruption in 1886. While the 1886 eruption was basaltic, study has shown there was only a small basalt component to the previous recent rhyolitic predominant eruptions. This eruption was one of New Zealand's largest historical eruptions, and killed an estimated 120 people. The fissures run for about 17 kilometres (11 mi) northeast–southwest
Lake Tikitapu, more commonly known as Blue Lake, is the smallest of four small lakes lying between Lake Rotorua and Lake Tarawera in the Bay of Plenty Region of New Zealand's North Island. The other three are Lake Rotokakahi, Lake Okareka, and Lake Okataina.
Te Wairoa was a village close to the shore of Lake Tarawera near Rotorua, New Zealand. The village was buried by volcanic ash in the 1886 eruption of Mount Tarawera. It was later excavated and is now open as a tourist destination, the Buried Village.
Lake Ōkataina is the northernmost and largest of four smaller lakes lying between Lake Rotorua and Lake Tarawera in the Bay of Plenty Region of New Zealand's North Island. The others are Lake Rotokakahi, Lake Tikitapu, and Lake Ōkareka. All lie within the Ōkataina caldera, along its western edge.
Lake Rotomahana is an 800-hectare (2,000-acre) lake in northern New Zealand, located 20 kilometres to the south-east of Rotorua. It is immediately south-west of the dormant volcano Mount Tarawera, and its geography was substantially altered by a major 1886 eruption of Mount Tarawera. Along with the mountain, it lies within the Ōkataina Caldera. It is the most recently formed larger natural lake in New Zealand, and the deepest in the Rotorua district.
Lake Tarawera is the largest of a series of lakes which surround the volcano Mount Tarawera in the North Island of New Zealand. Like the mountain, it lies within the Ōkataina Caldera. It is located 18 kilometres (11 mi) to the east of Rotorua, and beneath the peaks of the Tarawera massif i.e. Wahanga, Ruawahia, Tarawera and Koa. The lake's surface area is 39 square kilometres (15 sq mi).
Lake Rotorua is the second largest lake in the North Island of New Zealand by surface area, and covers 79.8 km2. With a mean depth of only 10 metres it is considerably smaller than nearby Lake Tarawera in terms of volume of water. It is located within the Rotorua Caldera in the Bay of Plenty Region.
The Waimangu Volcanic Rift Valley is the hydrothermal system created on 10 June 1886 by the volcanic eruption of Mount Tarawera, on the North Island of New Zealand. It encompasses Lake Rotomahana, the site of the Pink and White Terraces, as well as the location of the Waimangu Geyser, which was active from 1900 to 1904. The area has been increasingly accessible as a tourist attraction and contains Frying Pan Lake, which is the largest hot spring in the world, and the steaming and usually pale blue Inferno Crater Lake, the largest geyser-like feature in the world although the geyser itself cannot be seen since it plays at the bottom of the lake.
Tūhourangi is a Māori iwi of New Zealand with a rohe centered on Lake Tarawera, Lake Rotomahana, Lake Okaro, Lake Okareka, Lake Rotokākahi, Lake Tikitapu and Lake Rotorua.
Frying Pan Lake is the world's largest hot spring. It is located in the Echo Crater of the Waimangu Volcanic Rift Valley, New Zealand and its acidic water maintains a temperature of about 50 to 60 °C (122–140 °F). The Lake covers 38,000 square metres in part of the volcanic crater and the shallow lake is only 5.5 metres (18 ft) deep, but at vents, it can go down to 18.3 metres (60 ft).
The region around the city of Rotorua, in New Zealand's North Island, contains several lakes. From biggest to smallest, these are Lake Rotorua, Lake Tarawera, Lake Rotoiti, Lake Rotoma, Lake Okataina, Lake Rotoehu, Lake Rotomahana, Lake Rerewhakaaitu, Lake Rotokakahi, Lake Okareka and Lake Tikitapu. There are also four smaller lakes: Lake Okaro/Ngakaro, Lake Rotokawa, Lake Rotokawau and Lake Rotongata. Most of the lakes have formed due to volcanic activity. The region is part of the Taupo Volcanic Zone, the world's most active area of explosive silicic volcanic activity in geologically recent time.
Mita Taupopoki was a notable Māori tribal leader of New Zealand. He identified with Ngāti Wāhiao, a hapū (subtribe) of the Tūhourangi iwi of Te Arawa.
The 1886 eruption of Mount Tarawera was a violent volcanic eruption that occurred in the early hours of 10 June 1886 at Mount Tarawera, near Rotorua on New Zealand's North Island. The eruption reached an estimated Volcanic Explosivity Index of 5 and killed an estimated 120 people, making it the largest and deadliest in New Zealand during the past 500 years, a period that includes the entirety of European history in New Zealand. The eruption began at roughly 2:00 a.m. and lasted for approximately six hours, causing a 10-kilometre-high (6.2 mi) ash column, earthquakes, lightning, and explosions heard as far away as Blenheim in the South Island – more than 500 kilometres away. A 17-kilometre-long (11 mi) rift formed across the mountain and surrounding area during the eruption, starting from the Wahanga peak at the mountain's northern end and extending in a southwesterly direction, through Lake Rotomahana and forming the Waimangu Volcanic Rift Valley. This rift is where the basaltic dyke that fed the eruption reached the surface.
Lake Rotokawau is a small volcanic lake 4.1 km (2.5 mi) east of Lake Rotorua in the Bay of Plenty region of New Zealand's North Island. The name is also used for lakes in the Kaipara District, Chatham Islands, on Aupouri Peninsula and near Lake Waikare in Waikato. Access is via Lake Rotokawau Road, from SH30 at Tikitere. The lake is owned and managed by Ngāti Rangiteaorere.
Ōkataina Caldera is a volcanic caldera and its associated volcanoes located in Taupō Volcanic Zone of New Zealand's North Island. It has several actual or postulated sub calderas. The Ōkataina Caldera is just east of the smaller Rotorua Caldera and southwest of the much smaller Rotomā Embayment which is usually regarded as an associated volcano. It shows high rates of explosive rhyolitic volcanism although its last eruption was basaltic. The postulated Haroharo Caldera contained within it has sometimes been described in almost interchangeable terms with the Ōkataina Caldera or volcanic complex or centre and by other authors as a separate complex. Since 2010 other terms such as the Haroharo vent alignment, Utu Caldera, Matahina Caldera, Rotoiti Caldera and a postulated Kawerau Caldera are usually used rather than a Haroharo Caldera classification.
Maunga Kākaramea is a 743 metres (2,438 ft) high dacite volcano located between Rotorua and Taupō in the North Island Volcanic Plateau. It has multiple steaming features and a picturesque crater lake reached by a short walk from the nearest road and has a nearby geothermal area.
The Ōkareka Embayment is a volcanic feature in Taupo Volcanic Zone of New Zealand. It most significant recent volcanic eruption was about 15,700 years ago and this deposited the widespread Rotorua tephra that reached beyond Auckland.
Lake Rotomakariri was a lake which formerly existed in the basin that is now occupied by Lake Rotomahana, in the Bay of Plenty region of New Zealand's North Island. The lake's name was in contrast to the nearby Lake Rotomahana, which prior to the 1886 eruption of Mount Tarawera, was a shallower warm water lake. Prior to this eruption, Lake Rotomakariri sat in a shallow basin surrounded by marshes, draining into Lake Tarawera by Awapurohe Creek and Rotomahana's outflow of Kaiwaka Stream. The eruption of Mount Tarawera initially destroyed Lake Rotomakariri and its lakeside village with the loss of 19 lives, though water entering the new crater gradually refilled Lake Rotomakariri after volcanic activity subsided. As water accumulated over the decade after the eruption, Lake Rotomakariri was absorbed by the larger Lake Rotomahana, which eventually rose to about 36–48 m (118–157 ft) above its pre-eruption level due to the previous outflow of the basin being blocked by ashfall.
