The Hatepe eruption, named for the Hatepe Plinian pumice tephra layer, sometimes referred to as the Taupo eruption and dated to around 180 AD, was Lake Taupo's most recent major eruption. It is considered New Zealand's largest eruption during the last 20,000 years. The eruption ejected some 120 km3 (29 cu mi), a VEI 7 eruption, of which 30 km3 (7.2 cu mi) was ejected in the space of a few minutes. This makes it one of the most violent eruptions in the last 5000 years, comparable to the Minoan eruption in the 2nd millennium BC, the Tianchi eruption of Baekdu around 1000 AD and the 1815 eruption of Tambora. The resulting ash turned the sky red over Rome and China.
