Details for: Okataina
This large fissure system produced during a major explosive eruption at Tarawera in 1886 is one of the most dramatic features of the massive Okataina Volcanic Centre. Okataina is surrounded by extensive ignimbrite and pyroclastic sheets produced during caldera-forming eruptions. The subparallel NE-SW-trending Haroharo and Tarawera complexes consist of rhyolitic lava domes and associated lava flows that formed between about 15,000 and 800 years ago and impounded lakes against the margins of the Okataina ring structure.
