In 1755 a subsea earthquake in the Atlantic Ocean generated a tsunami attacking the coasts of Portugal, Spain and Morocco.
Lisbon was almost destroyed by the tsunami. DHI carried out a project for the Moroccoan goverment in order to investigate the possible location of a power plant to safeguard it against future tsunamis.
The initial movement of the water in the Atlantic Ocean from the 1755 tsunami has a level differens of 15 m and an extent of 400 by 800 km in the model setup.
The tsunami generated a measured (estimated) runup on the coasts of Morocco of approx 10 m above normal sea level. The model results gave from 8-13 m runup along the Moroccan coastline.
