The flat-topped Tarawera lava dome complex at the top of the photo to the NE is one of two large dome complexes forming the Okataina Volcanic Centre at the N end of the Taupo Volcanic Zone. An eruptive fissure that cuts the dome complex and extends across Lake Rotomahana to the foreground was the source of a major eruption in 1886. The Tarawera complex and the Haroharo complex off the photo to the left were both sources of major explosive eruptions during the Pleistocene and Holocene that produced large ignimbrite sheets.
