The 27 February 2010 Maule, Chile tsunami: initial height and propagation from uniform and non-uniform fault slip models

Abstract

The 27 February 2010 Maule (Chile) tsunami was numerically modeled using the SWAN (<strong>S</strong>imulating <strong>WA</strong>ves <strong>N</strong>ear-Shore) code which solves the non-linear long wave equations of fluid flow by a finite difference algorithm. The computational area is divided into two computational domains with a grid of 2 arc min and 0.5 arc min. Bathymetry data for the domains are interpolated from the General Bathymetry Chart of the Ocean (GEBCO) 30 arc-seconds grid data. Results from uniform and non-uniform slip models are compared with available tide gauges and Deep-ocean Assessment and Reporting of Tsunami (DART) buoy records.
