| Summary: | In Portugal, the Instituto de Meteorologia (IM) is the institution responsible for the Portuguese seismic network and it is the candidate to host the Portuguese Tsunami Warning System. One critical component of the system is the scenario database and the Tsunami Analysis Tool that help the operator to take decisions during the course of the event. This paper describes the progress done since 2008 conducting to the 3rd generation of the scenario database that provides a higher resolution modeling at the coastline for the whole North Atlantic. The 3rd generation scenarios are initiated by a simulation domain with a coarse bathymetry cell size (2 min). This initial calculation establishes the adequate initial and boundary conditions to 3 other domain calculations with a much finer cell size (0.25 min). The high-resolution calculation is performed only close to the coast in order to reduce the CPU time. JRC.G.2 - Global security and crisis management |
