The Haroharo volcanic complex is the NW-most of two lava dome complexes forming the Okataina Volcanic Centre. A 16 x 28 km wide caldera was formed incrementally during eruptions between 300,000 and 50,000 years ago. Its rim, seen in this photo across the caldera lake, is generally obscured by a group of overlying lava domes. All post-caldera domes are less than 20,000 years old, and the most recent Haroharo eruption took place about 3,500 years ago. Photo by Ian Nairn (Geological Survey of New Zealand).
