About the Event: 

This week marks the anniversary of the largest eruption in New Zealand in the 20th century – from Ruapehu Volcano on the 11th of October 1995. Ruapehu is one of two large stratovolcanoes in Tongariro National Park, and this talk discusses what has been learned in terms of the geology, volcanology and hazard at this dual world heritage site over the last 25 years. It discusses how physical, social and multi-disciplinary science have been brought together to support the Department of Conservation in communicating our understanding of the landscape; and in hazard management. In terms of physical science, we have newly realised the profound impact the fight between magma and ice has had on the shape of the mountains over more than 95% of their life histories. Our understanding of the magma systems, and development of monitoring and warning systems have advanced substantially, but the chance of sudden eruptions is always present. We will also touch on New Zealand eruptions since 1995, and what we have learned from each of these.
