The ElastoDynamics Toolbox is a MATLAB toolbox to model wave propagation in layered media. It is based on the direct stiffness method and the thin layer method [10, 12]. The toolbox can be used to solve a variety of problems governed by wave propagation in the soil: Site amplification Site amplification is an important issue in the assessment of the seismic hazard at sites where the top soil layers are particularly soft. In such cases, the seismic motion at the surface can be much higher than the outcrop motion due to resonance of the soft layers-This chapter describes how to start using the ElastoDynamics Toolbox (EDT) for MATLAB. The chapter is organized as follows: About the ElastoDynamics Toolbox (p. 1) The ElastoDynamics Toolbox for MATLAB is briefly introduced. Obtaining and installing EDT (p. 1) This section explains where to get EDT and how to install it. Terms of use (p. 3) The terms and conditions to use of EDT are summarized. It is shown how to re
