The Taupo Volcanic Zone is located on New Zealand's North Island. It is 350 kilometres (217 mi) long by 50 km wide (31 mi) and lies over a subduction zone in the Earth's crust. Mount Ruapehu marks its southwestern end, while the submarine Whakatane volcano (85 km or 53 mi beyond White Island) is considered its northeastern limit.[20] Many geysers in this zone were destroyed due to geothermal developments and a hydroelectric reservoir, but several dozen geysers still exist. In the beginning of the 20th century, the largest geyser ever known, theWaimangu Geyser existed in this zone. It began erupting in 1900 and erupted periodically for four years until a landslide changed the local water table. Eruptions of Waimangu would typically reach 160 metres (520 ft) and some superbursts are known to have reached 500 metres (1,600 ft).[14] Recent scientific work indicates that the Earth's crust below the zone may be as little as 5 kilometres (3 mi) thick. Beneath this lies a film of magma 50 km wide (31 mi) and 160 km long (99 mi).[
Due to the high rate of volcanic activity in Iceland, it is home to some famous geysers in the world. Geysers and hot springs are distributed all over the island. Many of the geysers are located in Haukadalur. Geysers are known to have
