Effect of Submarine Canyons on Tsunami Heights, Currents and Run-Up Off the Southeast Coast of India

Abstract

Comparisons between the tsunami wave energy density at 10 m depth and the onshore run-up height observations showed good correlation for select locations, with the run-up heights being about 3% of the wave energy density. However, the local topography in the run-up zone also strongly influences the local run-up, which reduces direct correlations between run-up and nearshore tsunami height.
