Seismic Wave Numerical Simulation Program Using High-Order Finite Difference Method

This program implements numerical simulation of seismic waves using high-order finite difference methods based on the acoustic wave equation. The code includes clear parameter documentation and comments, which is especially beneficial for those new to seismic wave numerical modeling. The implementation utilizes MATLAB's computational and graphical capabilities to directly generate visualization outputs. These outputs represent wavefield snapshots that illustrate seismic wave propagation patterns through different media. The simulation helps researchers better understand wave behavior characteristics, thereby contributing to improved earthquake prediction and impact assessment. Key algorithmic features include: high-order finite difference discretization of the wave equation, stability condition implementation, boundary condition handling, and time-domain wave propagation modeling. The MATLAB code structure allows for straightforward parameter modification and result visualization through built-in plotting functions.
