The upper image shows a computational model of a valley that has been automatically partitioned for solution on a parallel computing system, one processor to a color. The lower image shows the response of the valley as a function of frequency and position within the valley. It is well known that the response of a building to an earthquake is greatest when the frequency of the ground motion is close to the natural frequency of the building itself. These results show that damage can vary
considerably depending on building location and frequency characteristics. Obtaining this kind of information for large basins such as the Greater Los Angeles Basin requires high performance computing.
