QuakeSim
Encyclopedia
QuakeSim is a NASA
project for modeling earthquake
fault systems. It was started in 2001 with NASA funding as a follow up to the General Earthquake Models (GEM) initiative. The multi-scale nature of earthquakes requires integrating data types and models to fully simulate and understand the earthquake process. QuakeSim is a computational framework for modeling and understanding earthquake and tectonic processes.
QuakeSim focuses on modeling interseismic process though various boundary element, finite element, and analytical applications, which run on various platforms, including desktop and high-end computers. The QuakeTables database allows for modelers to access geological and geophysical data. A goal of QuakeSim is to develop significant improvements in earthquake forecast quality, thereby mitigating the danger from this natural hazard.
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 ground motion, allowing for the opportunity to improve structural response.

Earthquake
An earthquake is the result of a sudden release of energy in the Earth's crust that creates seismic waves. The seismicity, seismism or seismic activity of an area refers to the frequency, type and size of earthquakes experienced over a period of time...

QuakeSim Portal
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:- Facilities for accessing real-time and archival GPS data
- Time series analysis tools, including ST_Filter and RDAHMM
- Mesh generation and viscoelastic finite element simulation tools (GeoFEST)
- OkadaOkadaOkada may refer to:* Okada , commercial motorcycles in Nigeria* Okada , a Japanese name. People with the name include:** Doris Matsui , American politician of the Democratic Party...

Developed Software
QuakeSim includes several applications. GeoFEST, PARK, and Virtual California are used to model different aspects of the earthquake cycle. For more information on these programs, and to download them, see the "Download Code" section of the QuakeSim website.QuakeSim-related NASA missions
