The Chile earthquake of 2010 was a severe earthquake that occurred on February 27, 2010, off the coast of south-central Chile, causing widespread damage on land and triggering a tsunami that devastated several coastal areas of the country. The epicentre was located 325 km southwest of the Chilean capital of Santiago, and the focus occurred at a depth of about 35 km below the surface of the Pacific Ocean. We conduct the 2D shallow-water simulation of a Chile tsunami scenario in ExaHyPE2, using realistic NetCDF bathymetry and earthquake displacement by ADER-DG solver with an FV limiter.
The mathematical model is again the two-dimensional nonlinear shallow-water equations in terms of the water depth \( h \), depth-averaged momenta \( hu \) and \( hv \), and sea-floor topography \( z \). The computational domain is a \( 4 \times 10^6 m\) by \( 4 \times 10^6 m\) rectangle, shifted by an offset \( [3\times 10^6, 0] \) in the global coordinate system to cover the relevant region off the Chilean coast. The pre-earthquake bathymetry and coseismic seafloor displacement are read from NetCDF datasets.
