Abstract

The role of the edge waves during the propagation of the tsunamis has been observed in nature. In this paper we study the features of the tsunamis generated by landslides around a conical island to understand the propagation and trapping mechanisms of the waves. Run-up measurements have been processed with the wavenumber-frequency analysis (k-f) to identify the dispersion relation followed by the waves that propagate alongshore. It is shown that the 0th-order edge waves mode is the only one relevant for shoreline run-up. Furthermore, a detailed two-dimensional k-f revealed that other waves modes play a role during the propagation.
