Abstract by Garret Carver
East Java tsunami hazard
A study of what the newly-discovered imbricate coastal boulder accumulations near Pacitan and at Pantai Papuma tell us. We claim that by current equations used to model the forces needed to move these boulders indicate that these boulders were likely placed by tsunamis rather than storm waves because the size of the storm waves needed to do so is not viable. We discuss the progress in the physical equations that describe boulder imbrication, specifically the revisions to Nott's 2003 equations. Our hope is that these findings will add information about past tsunamis to predict future events in the area.
