CCA GTL

CCA GTL

CCA (scientific name is Central California Area model) is a tomopgraphy improved version of CVM-S4 and Cencal, a USGS northern California model. The tomography produced a cell-based velocity model with an option GTL that is set off by default. The GTL is enabled in the model/config file. The elygtl can also be added to this model.

The first vertical profile plotted below is at location USC:

• LAT=34.0224
• LON=-118.2851
• STEP=1
• START_depth=0
• END_depth=1000

The second vertical profile plotted below is location near Ridgecrest at: LAT=35.5 LON=-117.5
