The eruption further expanded the lake, which had formed after the much larger Oruanui eruption. Its new deposits also briefly created another large lake to the Taupō Volcano's north that extended to the Reporoa Caldera which in due course broke out into the Waikato River valley and released over a short period 2.5 km 3 (0.60 cu mi) of water.
In due course after the Hatepe eruption the lake that formed further expanded on the lake that had formed after the much larger Oruanui eruption around 26,500 years ago. The previous outlet was blocked, raising the lake 35 meters (115 feet) above its present level until it broke out after about 20 years in a huge flood. [ 6 ]
Lake Taupō (also spelled Taupo; Māori: Taupō-nui-a-Tia or Taupōmoana) is a large crater lake in New Zealand's North Island, located in the caldera of Taupō Volcano. The lake is the namesake of the town of Taupō , which sits on a bay in the lake's northeastern shore.
At the time of the eruption, the sea level was much lower than at present, and for over 100,000 years the Taupō Volcano had been mainly under Lake Huka, a larger lake than the present Lake Taupō. [1]: 6 Lake Huka was destroyed in the eruption, and other features of the local geography were changed significantly as outlined below.
The last major eruption from Lake Taupō, the Hatepe eruption, occurred in 232 CE. [6] It is believed to have first emptied the lake, then followed that feat with a pyroclastic flow that covered about 20,000 km 2 (7,700 sq mi) of land with volcanic ash .
Mount Tauhara is a dormant lava dome [1] volcano in New Zealand's North Island, reaching 1,088 metres (3,570 ft) above sea level.It is situated in the area of caldera rim overlap of the Whakamaru Caldera and Taupō Volcano towards the centre of the Taupō Volcanic Zone, which stretches from Whakaari / White Island in the north to Mount Ruapehu in the south.

The reefs are at a high heat-output geothermal hot spot area within the Taupō Volcano. [3] This is related to rhyolitic lava domes extruded after explosive volcanism. [4] The explosive eruptions include the VEI 7 Hatepe eruption of 232 ± 10 CE that ejected over 120 km 3 (29 cu mi) of material (also known as Horomatangi Reef Unit Y eruption) [5] and its linear line of eruption centres, [6] as ...
New Zealand's flora is still recovering from the last glacial maximum. About 2 Ma, extension and subduction under the North Island formed the Taupo Volcanic Zone, leading to the central North Island being covered in cobalt deficient soils which restrict forest development. One of the largest eruptions being the Lake Taupo eruption of 186 AD. [44]
