“…The Atlantic Ocean, a low rate expanding ocean (the average spreading rate of the mid-ocean ridge is estimated around 2.5 cm yr −1 ), is not bordered by a fire belt like the Pacific Ocean, but shows however some particular places to monitor and able to trigger some catastrophic tsunamis according to available tsunami databases (Gusiakov and Mercado, 2002;Lander et al, 2002;Baptista and Miranda, 2009;Baptista et al, 2011;NGDC, 2013) and geological settings. These tsunami generating zones are split in two parts: in one hand, the active zones, represented by convergent plate boundaries: the Antilles subduction zone for the western side of the Atlantic, which generated several local or regional tsunamis as for example the 1867 Virgin Islands event (Zahibo et al, 2003;Barkan and ten Brink, 2010), and the Iberian Peninsula fault system for the eastern side, especially known because of the 1755 "Lisbon" tsunami, which was historically recorded at lots of locations in the Northern Atlantic Ocean including the Lesser Antilles (Barkan et al, 2009;Roger et al, 2010a, b, c).…”
