QuakeSim

<h2 id="quakesim-portal">QuakeSim Portal</h2>
<p>The QuakeSim Portal allows for users to access and ingest data into models and simulations.  It provides the computational infrastructure for the entire project. QuakeSim users can create an account and interact with different data and software through the portal. The QuakeSim Portal consists of portlets that include:
</p>
<ul><li>Facilities for accessing real-time and archival <a href="/facts/GPS/DKVLnzF3">GPS</a> data</li>
<li>Time series analysis tools, including ST_Filter and RDAHMM</li>
<li>Mesh generation and viscoelastic finite element simulation tools (GeoFEST)</li>
<li>Okada-based elastic fault modeling methods (Disloc, which is a forward model, and Simplex for inverting geodetic data).</li></ul>
<h2 id="quaketables">QuakeTables</h2>
<p>QuakeTables is the database used to access information for QuakeSim.  Information found in the QuakeTables includes:
</p>
<ul><li><a href="/facts/Paleoseismic/63KbDggp">Paleoseismic</a> fault data</li>
<li>Global Positioning System (GPS) surface deformation data</li>
<li>Seismicity data</li>
<li>Processed Interferometric Synthetic Aperture Radar (<a href="/facts/InSAR/JBdVTnVz">InSAR</a>) Interferograms from existing satellites</li></ul>
<p>This information plays a big role in the process of forecasting and damage mitigation.  The information allows for the creation of simulations and data mining.  This then improves the prediction for potential earthquakes.  This, along with attenuation modeling and site effects, leads to a better understanding of probable <a href="/facts/Ground_motion/0xdovg74">ground motion</a>, allowing for the opportunity to improve structural response.
</p>

<h2 id="developed-software">Developed Software</h2>
<p>QuakeSim includes several applications. GeoFEST, PARK, and Virtual California are used to model different aspects of the earthquake cycle.

<h2 id="quakesim-related-nasa-missions">QuakeSim-related NASA missions</h2>
<p>QuakeSim utilizes GPS data from <a href="/facts/NASA/TIMCV0yV">NASA</a>, the <a href="/facts/National_Science_Foundation/FlDT8TbW">National Science Foundation</a>, and the <a href="/facts/US_Geological_Survey/nVaGtMjl">US Geological Survey</a> Southern California Integrated GPS Network (SCIGN). QuakeSim was also establishing the computational infrastructure for the planned NASA DESDynI (Deformation, Ecosystem Structure, and Dynamics of Ice) mission, which was cancelled in 2012.<a class="footnote-ref" id="fnref:1" href="#fn:1"><sup>1</sup></a>
DESDynI (pronounced destiny) would fly <a href="/facts/InSAR/JBdVTnVz">InSAR</a> and <a href="/facts/LIDAR/b9SPUmLM">LIDAR</a> instruments for studying hazards and global environmental change.
