The M_w 7 Haiti earthquake in 2010 was accompanied by local tsunamis that caused fatalities and damage to coastal infrastructure. Earthquakes alone could not explain all observations in Hispaniola Island. We suspected that a big submarine landslide occured and generated the 3 m high waves observed near Jacmel and Pedernales. We identify a landslide scar 30 km from the epicenter and at a depth of 3500 m and we simulate the corresponding tsunami which gives results very close to observations.

The objective of this paper is to present a new methodology for the analysis of the seismic induced tsunami hazard. The proposed methodology mainly relies on uncertainty quantification techniques and the construction and validation of some emulators, or meta-models, used instead of the original models for the construction of a numerical tsunamis database. The methodology was tested with tsunamis generated by the Azores-Gibraltar Fracture Zone and potentially impacting the French Coast.
