Tsunamis are a great threat to densely populated coastal areas like the U.S. east coast. They have a variety of triggering mechanisms, one being underwater landslides. In past research the tsunami hazard from earthquake triggered submarine landslides on the U.S. east coast was assessed. The objective of this thesis was to refine the slope stability calculations from the previous research for four chosen study areas. To achieve this, data on the bathymetry, soil properties, lithology, and seismicity was improved. New data was collected and shear wave velocities were synthesized using a Biot Gassmann model. The synthesized data was used to perform a site response analysis which showed that the peak ground accelerations decreased as they propagated up through the soil profile. A seismic coefficient for the slope stability analyses was developed and the final slope stability calculations were carried out based on a pseudo-static limit equilibrium method. The results from these calculations suggest that the continental slope within the four study areas is stable, whereas the canyons showed large probabilities of failure under the applied earthquake loads.
