Short summary
The Mw 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.
