The 1886 Tarawera eruptive fissure, seen from the N, formed across lava domes of the 800-year-old Kaharoa eruption. The red and black rocks of the 1886 eruption, 20-30 m thick here, overlie white rhyolitic Kaharoa eruption deposits. This view shows a 2-km-long section of the 8-km en-echelon fissure with gray rocks of the Ruawahia lava dome appearing at the far end. Photo by Bruce Houghton (Wairakei Research Center).
