The Volcanic Origins of Lake Taupo:

In 186 AD a series of nine volcanic eruptions culminated in the most violent eruption history has recorded. In a few short minutes 30 square km of poisonous ash, rocks, lava and pumice were emitted at speed of up to 900 km/hr, to a height of 50 km. Such was the extent of the volcanic fallout, even the ancient Romans and Chinese are reported to have experienced darkened skies. The debris was deposited some 30,000 square km wide to a depth of tens of metres thick in some places. The whole of the North Island was coated in a thick, toxic ash, which destroyed entire forests. Lake Taupo was formed in the crater left by the eruption and remains volcanically active (something you'll notice as you swim through pockets of much warmer water, heated by thermal activity in lake's depths). Today, at 359 m above sea level, the lake measures 616 square km and is 159 m at its deepest.
