The steaming Waimangu hot pool is located near the southern end of the 1886 Tarawera eruptive fissure. Intermittent phreatic eruptions took place from this and other craters south of Lake Rotomahana from 1886 until as recently as 1973. Waimangu (black water) geyser was active from 1900 until activity ceased on 1 November 1904.
