Efficient Forward Modelling of Tsunamis Using the Spectral-Element Method

Description: 

We developed an open-source tool for the forward modelling of tsunamis. We utilize the spectral element method, aiming to enhance the accuracy and efficiency of tsunami simulations. The spectral element method is a higher-order finite element method that is extensively used in forward and adjoint modelling of seismic wave propagation due to its inherent advantages, such as higher accuracy, stability, and efficiency. Specifically, we solve the shallow water wave equation on curvilinear coordinates to accommodate Earth's curvature. We employ ETOPO 2022 as a reference for the bathymetry. We perform comprehensive simulations of the Indian Ocean tsunami induced by the 2004 Sumatra-Andaman Earthquake and the Pacific Ocean tsunami induced by the 2010 Chilean earthquake.
