QuakeSim Computational Infrastructure for Integrating DESDynI and UAVSAR Data into Earthquake Models (Invited)
Abstract
QuakeSim is a computational infrastructure for studying, modeling, and forecasting earthquakes from a system perspective. QuakeSim takes into account the entire earthquake cycle of strain accumulation and release, requiring crustal deformation data as a key data source. Interferometric Synthetic Aperture Radar (InSAR) and Global Positioning System (GPS) data provide current crustal deformation rates, while paleoseismic data provide long-term fault slip rates and earthquake history. The QuakeTables federated multimedia database contains spaceborne and UAVSAR InSAR data for the California region as well as paleoseismic fault data from a number of self-consistent datasets, such as the Uniform California Earthquake Rupture Forecast (UCERF), California Geological Survey (CGS), and Virtual California. Access to QuakeTables is provided through a web interface and a Web Services based application program interface (API) for data delivery. Data are categorized into self-consistent datasets that can be queried in their original form or a derivation therefrom. QuakeTables provides access to mapping features through a web interface, that provides users with direct access to the QuakeTables federated data. Users can browse, map and navigate the available datasets. QuakeSim applications include crustal deformation modeling and pattern analysis. The crustal deformation tools include forward elastic dislocation models (DISLOC) and 3D viscoelastic finite element models (GeoFEST), and elastic inversions of crustal deformation data (SIMPLEX). The tools support mapping and applications for visualizing results in vector or interfermetric form. Virtual California simulates interacting fault systems. Pattern analysis tools include RDAHMM for identifying state changes in time series data, and RIPI for identifying hotspot locations of increased probabilities for magnitude 5 and above earthquakes. The QuakeSim infrastructure automatically posts UAVSAR data to QuakeTables for storage and modeling establishing infrastructure for doing the same for DESDynI data when they are available.
