Velocity Model Image
A VirtualBox image file (also known as an Appliance file) containing the UCVM software and 4 California Velocity models is available for download from a SCEC server. This link will download a large file, and, depending on your network connection, it may take 30 minutes, or more, to download.
- UCVM SSA 2019 Virtual Box Image(17GB download from SCEC servers)
md5sum for Image file
Since this is a large file, you can check the integrity of the downloaded file using md5sum tools: On a Linux system, download the md5sum file, then run the following command: md5 checksum file for Linux to verify the image file
$ md5sum -c ucvm_ssa_2019.ova.md5
On a mac, you can check the file using the md5 utility: md5 on Mac:
$ MD5 (ucvm_ssa_2019.ova) = e4f4597beccb42c3ad708d5972380bfc
