SCEC's CVM evaluation system is designed to show differences between currently available California CVM's. Our CVM evaluations use wave propagation simulations of moderate magnitude historical earthquakes.
When a CVM is registered with the CVM evaluation system, three things happen:
- A software distribution of the CVM is posted online so that it is accessible to the SCEC Community
- The CVM is used so construct a velocity mesh for a 1Hz Chino Hills simulation. In the future, additional validation events may be used.
- The system runs a 1Hz wave propagation simulation and compares simulation results to observed seismograms for the event
- Evaluation results, including velocity profile plots, and waveform-based goodness of fit measures are posted for all registered CVM's.
Recent CVM Evaluations
CVM evaluations are typically run when new CVM's are released. In Feb, 2011, we released CVM-H v11.2. At this time, we ran CVM evaluations for three different SCEC CVM's including:
Evaluation results for CVM-H v11.2 and other SCEC CVM's are posted here:
Example Goodness of Fit Measures
Our CVM Evaluation system uses several goodness of fit measures. As one example, here are frequency dependent, amplitude-based, bias plots used in the CVM evaluation process.
