AB HySEA tsunami model is used to simulate the Caribbean LANTEX 2013 scenario. Thenumerical simulation of the propagation and inundation phases is performed with a single integratedmodel but using different mesh resolutions and nested meshes. Special emphasis is put on assessingthe most exposed coastal areas at Puerto Rico affected by this event. Comparisons with MOST aremade considering both time series at different locations, and inundation maps. Both modelscompare well for propagating tsunami waves in open sea, producing very similar results. The maindiscrepancies are observed in coastal areas, where maximum wave height provided by thepropagation module of MOST is different from the one provided by HySEA. The main reason isthat, while HySEA always compute inundation effects, MOST propagation does not include runupphysics and locates an artificial numerical reflecting wall at a certain depth (typically 20 m).Henceforth, in nearshore shallow waters HySEA should be compared with the inundation version ofMOST. Nevertheless the most striking difference resides in computational time; HySEA is codedusing the advantages of GPU architecture, and can produce a 4 hour simulation in a 60 arc-secresolution for the whole Caribbean Sea in less than 4 min with a single GPU and as fast as 11seconds with 32 GPUs. When details about the inundation must be simulated, a 1 arc-sec(approximately 30 m) inundation resolution mesh covering all of Puerto Rico, an island withdimensions of 160 km east-west and 56 km north-south, is used, and a three level nested meshestechnique implemented. In this case approximately 11 hours of wall clock time are needed for a 2hour simulation in a single GPU.
