In this talk, I will first focus on deriving the wave equation for an elastic medium, followed by a discussion on its Green's function solution, which incorporates the moment tensor representation of seismic sources. The moment tensor, which is a second-rank tensor, characterizes seismic sources by using the slip direction of an earthquake and the fault's normal. Moreover, the magnitude of an earthquake is proportionally related to the norm of moment tensor. The structure of the space of moment tensor will be explained, along with the elasticity tensor which is a critical component for the moment tensor's definition.
