ABSTRACT BODY: The QuakeSim science gateway environment includes a visually rich portal interface, web service access to

data and data processing operations, and the QuakeTables ontology-based database of fault models and sensor data. The

integrated tools and services are designed to assist investigators by covering the entire earthquake cycle of strain accumulation

and release. The Web interface now includes Drupal-based access to diverse and changing content, with new ability to access

data and data processing directly from the public page, as well as the traditional project management areas that require password

access. The system is designed to make initial browsing of fault models and deformation data particularly engaging for new users.

Popular data and data processing include GPS time series with data mining techniques to find anomalies in time and space,

experimental forecasting methods based on catalogue seismicity, faulted deformation models (both half-space and finite element),

and model-based inversion of sensor data. The fault models include the CGS and UCERF 2.0 faults of California and are easily

augmented with self-consistent fault models from other regions. The QuakeTables deformation data include the comprehensive

set of UAVSAR interferograms as well as a growing collection of satellite InSAR data.. Fault interaction simulations are also being

incorporated in the web environment based on Virtual California.

A sample usage scenario is presented which follows an investigation of UAVSAR data from viewing as an overlay in Google Maps,

to selection of an area of interest via a polygon tool, to fast extraction of the relevant correlation and phase information from large

data files, to a model inversion of fault slip followed by calculation and display of a synthetic model interferogram.
