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
