gridding code that can integrate scattered and heterogeneous geophysical data
sets. Will Savran has made many recent contributions to the code.
- Try the MA-CME 5.3.1 GUI: The ModelAssembler Community Modeling
Environment has a tutorial graphical interface that sets up the input
file for earthquake-scenario modeling runs with LLNL's E3D or WPP codes.
- An MA-CME Bibliography
- The Viewmat package of the Resource Geology Seismic Processing
System for Java, for visualizing velocity volumes and shaking maps.
