In which country is Waimangu Volcanic Rift Valley located?
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. The four-kilometre (2.5 mi) stretch of the Waimangu Volcanic Rift Valley running from Southern Crater to the shores of Lake Rotomahana has been a hotspot of geothermal and hydrothermal activity since the 1886 Mount Tarawera eruption, and contains the three lake-filled craters Southern Crater, Echo Crater, and Inferno Crater, as well as the bush-clad Raupo Pond Crater, Fairy Crater and Black Crater.
The 50-metre-deep (160 ft) Southern Crater was formed by the 1886 Mount Tarawera eruption and has not been notably active since. Its floor is filled by the shallow two-metre-deep (6.6 ft) Emerald Pool, a cold water lake of mostly rainwater. The lake's water is usually a brown colour, but can vary depending on the state of the plants growing in it. Red aquatic fern growth is sometimes present.
