The Need For a Decision Support System In Tsunami Early Warning Practice In Case of Near-shore Sources

From a Tsunami Early Warning System (TEWS) design perspective, this paper presents few theoretical cases of earthquakeand landslidegenerated tsunamis in western Iberia and in the eastern Mediterranean, with the aim of discussing the need for a Decision Support System integrating suitable real-time sensor networks of different types and a properly-designed knowledge-based archive of scenarios. The advantages of this type of approach over simpler tools, such as Decision Matrices, are briefly discussed.
