GNGTS 2017 - 36° Convegno Nazionale

226 GNGTS 2017 S essione 2.1 approach to tsunami generation and linear propagation across the sea up to an offshore fixed depth; 3) the use of approximations for shoaling and inundation, based on local bathymetry, and for tidal stages (Glimsdal et al. , 2017; Selva et al. , 2017); and 4) the exploration of several alternatives for the basic input data and their parameters which produces a number of models that are treated through an ensemble uncertainty quantification (Selva et al. , 2016) which includes a formalized elicitation (Selva et al. , 2017, TSUMAPS-NEAM TI Team, 2017). The hazard results can be summarized as follows: • hazard curves calculated at 2,343 POIs (Points Of Interest; North-East Atlantic: 1,076; Mediterranean Sea: 1,130; Black Sea: 137) at an average spacing of ~ 20 km; • for each curve, hazard values for mean, 2nd, 16th, 50th, 84th, 98th percentiles; • probability maps for MIH (Maximum Inundation Height) 0.5, 1, 5, 10, 20 meters; • hazard maps for 1/100 years; 1/1,000 years; 1/10,000 years ARP (Average Return Period); • interactive Hazard Map and Curve Tool (Fig. 2). Along with the above listed results, the project and its collaborative framework (ASTARTE, CAT) produced the following ready-to-use by-products: • database of pre-calculated tsunami scenarios for over 120,000 elementary sources for c. 30 Terabytes, covering an area of c. 6x10 6 km 2 (see Molinari et al. , 2016, for the method and implementation; the tsunami numerical simulations are performed with Tsunami-HySEA, Macías et al. , 2017); • hazard calculation platform; • amplification factors (Glimsdal et al. , 2017).
