CVM-H 15.1.0 Comparison

Introduction

CVM-H 15.1.0 is the proposed new community velocity model that updates CVM-H 11.9.1 with the addition of the Santa Maria Basin.

Comparison Method

CVM-H 15.1.0 was built by removing the model files CVM_LR_TAG@@, CVM_LR_VP@@, and CVM_LR_VS@@ and replacing them with CVMSM_tag66@@, CVMSM_vp66@@, and CVMSM_vs66@@. The low resolution configuration file was modified to use these updated files instead. These were the files provided by Harvard. A binary comparison between the respective files revealed that they do differ (e.g. CVMSM_tag66@@ and CVM_LR_TAG@@ are different files).

UCVM 14.3.0 was used to create a cross-section of both models from (-120.49, 34.62) to (-120.10, 34.90) starting at 0m and going to 5km depth. The horizontal and vertical resolution were both 20m.
