Deligne, N.I.; Wilson, G. 2015 Architecture and hazard intensity metrics for RiskScape volcano. Lower Hutt, N.Z.: GNS Science. GNS Science report 2015/19 23 p.
Abstract: RiskScape is a multi-hazard risk assessment platform jointly developed by GNS Science and the National Institute of Water and Atmospheric Research. RiskScape has a modular structure: risk evaluation is based on a hazard, an asset, and a vulnerability module. Here we document changes to the volcanic hazard module in RiskScape. To date, volcanic ash (tephra fall) has been the sole volcanic hazard considered in RiskScape. We are changing the architecture of RiskScape volcano to be eruption-driven, such that one eruption scenario can include not only a volcanic ash layer, but also layers of pyroclastic density currents, lahars, lava flows, and the creation of a volcanic edifice. We briefly describe each of these five volcanic hazards and the hazard intensity metric(s) adopted to characterise the hazard in RiskScape. Finally, we outline future work intended for the RiskScape volcano hazard module. (auth)
