Handling Uncertainty in Tsunami Early Warning: Interaction between Decision Support and Multi-Sensor Simulation System

Kurzfassung

The new InaTEWS/GITEWS tsunami early warning system has been designed to work reliably and quickly in the special case of near-field tsunamis with extremely short warning times. In order to avoid false warnings this system is equipped with a multi-sensor simulation system which can evaluate multiple online measurement values simultaneously. With this system, within short time a reliable small number of scenarios can be selected to serve as an early situation assessment. However, in order to support a decision maker for issuing warning products, a thorough analysis of the simulation results and a blending with additional geographic and socio-economic information is necessary. In this paper the interplay between decision support system and simulation system is illustrated.
