This project aims to develop and apply a holistic framework for tsunami vulnerability assessment of critical infrastructure. • Develop tsunami vulnerability functions for infrastructure which consider a range of: -Lifeline utilities network components -Hazard intensity measures -Impact types • Apply synthesised vulnerability functions to a New Zealand-based

Impact assessment is important for proactive tsunami risk management. However, research on tsunami vulnerability of infrastructure lifelines is largely under-developed. Tsunami vulnerability functions typically use depth as a proxy for direct damage. We aim to develop new functions which consider a range of construction standards (material etc.) hazard intensity measures (depth, speed, loading etc.) and impact types (direct damage, level of service etc.).
