The Kaharoa eruption about 700 years ago was the first Holocene eruption of the Tarawera lava dome complex in the Okataina Volcanic Centre. It produced an extensive rhyolitic tephra deposit that extended to the E coast of North Island. Geologist Pat Brown examines a charcoalized log within a pyroclastic flow deposit from this eruption. The upper part of the section consists of blocky debris from collapse of a rhyolitic lava dome at the end of the eruption.
