Fault Plane Strike / Dip / Rake: 340 / 45 / 90

Fault centre Lat / Lon: 37.0N / 9.75W (SW Lisbon)

L = 210 km, W = 75 km, D = 13.6 m

WP7.3 Simulation of the 1755 tsunami in the “Boca do Rio” area

WP7.3 Simulation of the 1755 tsunami along Algarve

Does Inundation correlate well to sedimentological evidence?
