Ground Motion Simulation of Moon Basin

As the initial trial of the project,
Earthquake Ground Motion Modeling in Large Basins, the half moon basin
was used to test our theories, methodologies, and techniques.

There are four cases done for a given
input Ricker's pulse

Here are the figures we have been preparing for a paper to be published
to BSSA later
