About QuakeSim
Objectives
 QuakeSim architecture |
QuakeSim is a project to develop a solid Earth science framework for modeling and understanding earthquake and tectonic processes. The multi-scale nature of earthquakes requires integrating many data types and models to fully simulate and understand the earthquake process. QuakeSim focuses on modeling the interseismic process through various boundary element, finite element, and analytic applications, which run on various platforms including desktop and high end computers. We integrate and deliver data products through our QuakeTables database.
- Provide improved modeling capabilities for understanding of earthquake and tectonic processes in order to improve earthquake forecasting.
- Make NASA crustal deformation, seismic and geologic data, and various earthquake simulation models available to the broader earthquake science community.
- Develop infrastructure to assimilate and model the large data volumes from airborne and spaceborne InSAR platforms.
Data
 Fusing GPS time series and InSAR data captures time dependent and spatial characteristics of deformation |
QuakeSim aims to simplify data discovery, access, and usage by making data available to modelers and model applications. Data are available through the QuakeTables interface.
- Paleoseismic fault data
- Surface deformation data in the form of
- Global Positioning System (GPS) data
- Processed Interferometric Synthetic Aperture Radar (InSAR) interferograms from existing satellites and airborne UAVSAR
- Seismicity data
Capabilities
 UAVSAR repeat pass interferometry products provide displacement and disturbance map |
Applications allow scientists to assimilate distributed data sources and complex models into a parallel high-performance earthquake simulation and forecasting system. With UAVSAR becoming operational QuakeSim has an increasing focus on analysis of radar interferograms (InSAR) and integrating them into modeling applications. The goal is to simplify data discovery, access, and usage from the scientific user point of view. QuakeSim also provides capabilities for efficient data mining and pattern recognizers for analyzing data and simulations. QuakeSim establishes the infrastructure and optimal techniques to understand the relationship between the observable space-time patterns of earthquakes and the underlying, nonlinear stress-strain dynamics.
