A chart compares SCEC simulations to observations from the 2008 Chino Hills earthquake.

These two Los Angeles area maps compare ground motions calculated by SCEC earthquake simulations to ground motions observed during the 2008 Chino Hills earthquake. On each map, the star marks the quake's epicenter, and the dots show locations where ground motions were recorded for that earthquake. The color variations show how well the simulated ground motions match the observed ground motions, with darker colors (from red to black) indicating areas with poorer matches and lighter colors (from yellow to white) indicating areas with good matches. The two maps show results from simulations using different 3-D Earth structure models. The Earth model that produced the best overall match to observations (shown here on the left) was the model used as input for the team's recent 1 hertz CyberShake seismic hazard simulation on the Blue Waters supercomputer.
