![]() QuakeSim provides model and analysis tools, computational infrastructure, access to data and an interface for understanding the complete cycle of earthquakes. Its varied applications include scientific studies, developing earthquake hazard maps that can be used for targeted retrofitting of earthquake-vulnerable structures, providing input for damage and loss estimates after earthquakes, guiding disaster response efforts, and studying fluid changes in reservoirs, among others. Studies have shown QuakeSim to be the most accurate tool of its kind for intermediate earthquake forecasting and detecting the subtle, transient deformation in Earth's crust that precedes and follows earthquakes. QuakeSim also is used to identify regions of increased earthquake probabilities called hotspots. This provides long-term histories of fault behavior that can be used for statistical evaluation. Initiated in 2002, QuakeSim uses NASA remote sensing and other earthquake-related data to simulate and model the behavior of faults in 3-D both individually and as part of complex, interacting systems. QuakeSim, developed at NASA's Jet Propulsion Laboratory in Pasadena, Calif., is a comprehensive, state-of-the-art software tool for simulating and understanding earthquake fault processes and improving earthquake forecasting. The award recognizes innovative software technologies that significantly improve the agency's exploration of space and maximize scientific discovery on Earth. NASA software that models the behavior of earthquake faults to improve earthquake forecasting and our understanding of earthquake processes, and NASA's first mobile application are co-winners of NASA's 2012 Software of the Year Award.
