Assessment of the tsunami hazard on Moroccan coasts using numerical modeling

Abstract

Caused by earthquakes in the marine environment, tsunamis are often of particular violence. Pests, their damage far exceeds those caused by earthquakes earthquakes. In Morocco, seismic sensors in the national network often detect earthquakes in the marine environment. However, specialists minimize their threat given the peculiarity of the Moroccan ocean zone. The latter is characterized by the importance of the length of the faults and the depth of the seismic focus. This work can be considered as a first approach to the study and understanding tsunamis. Although Morocco has known since historical times, earthquakes and tsunamis along its coasts. This preliminary study is mainly intended to show the contribution of the numerical simulation of tsunamis, with a concrete application of the 1755 Tsunami of Lisbon based on the four source zones involving the five potentially tsunamigenic faults that are generally mentioned in the literature for this major event.
