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.

Here we present new numerical simulations showing that Holocene submarine landslides along the North Anatolian Fault in the Aegean Sea may have triggered tsunamis higher than the ones expected for earthquake sources. During the Holocene, the shore facing the city of Alexandroupoli may have been impacted by tsunami up to 1.65 m at the coastline.

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.
