This research focused on improving mass-flow hazard assessments at New Zealand volcanoes using a combination of computer models and geological mapping. On Mt. Ruapehu, a new simulation model, Titan2D, was adapted and tested for forecasting the behaviour of lahars in the Whangaehu River, with special focus on the lahar from Crater Lake on the 18th March 2007. On Mt. Taranaki , the simulations were accompanied by geological mapping to provide new insights into the flow and deposition of large-scale debris avalanches, as well as the resultant process of landscape recovery following these catastrophic events. In addition, methods were developed to apply computer simulations for forecasting a range of the most common types of small-scale hot and cold mass flows expected from any re-awakening of Mt. Taranaki. The study culminated in the production of new dynamic hazard maps in electronic format that are more useful for land-use planners and emergency managers.
