Earthquake-generated tsunamis near the Africa-Eurasia collision zone: cases studies for tsunami hazard evaluation in the Mediterranean Sea and the northern Atlantic Ocean
The main objective of this thesis is to improve the knowledge of tsunami hazard in Western Mediterranean and Northern Atlantic. It focusses on earthquake-generated tsunamis which present the advantage to be preceded by a useful precursor for the warning, that can be felt by the population: the earth...

The main objective of this thesis is to improve the knowledge of tsunami hazard in Western Mediterranean and Northern Atlantic. It focusses on earthquake-generated tsunamis which present the advantage to be preceded by a useful precursor for the warning, that can be felt by the population: the earthquake. Two types of studies are presented, using numerical modelling. It allows to built maximum wave height maps for each scenario, determine arrival times, inundation zones and study resonance phenomenon. The first studies concern the tsunami impact induced by seismic sources (rupture parameters) proposed by previous studies (the 1755 tsunami in the West Indies or in Newfoundland and the 2003 tsunami of Zemmouri in Southern France).
