Exciting news! We're transitioning to the Statewide California Earthquake Center. Our new website is under construction, but we'll continue using this website for SCEC business in the meantime. We're also archiving the Southern Center site to preserve its rich history. A new and improved platform is coming soon!

The Unified Community Velocity Model (UCVM) software framework facilitates the registration and distribution of seismic velocity models to the SCEC community. It is designed to provide a standard query interface to multiple, alternative velocity models, even if the underlying velocity models are defined in different formats or use different geographic projections. The UCVM framework helps researchers compare seismic velocity models and build equivalent simulation meshes from alternative velocity models. The UCVM framework provides a comprehensive set of open-source tools for querying seismic velocity model properties, combining regional 3D models and 1D background models, visualizing 3D mode...ls, and generating computational models in the form of regular grids or unstructured meshes that can be used as input for ground-motion simulations. In this poster, we describe recent improvements made to UCVM. We have registered additional velocity models into UCVM including the Albacore offshore model, Coachella and Imperial Valley models, and an updated Wasatch Front model. We have developed a UCVM web interface that provides access to the velocity models registered in UCVM and allows users to query the models and create plots without installing UCVM. And, to simplify the installation of UCVM, we have posted UCVM images on Dockerhub which can retrieved, installed, and run on a wider variety of computers including Mac, Windows, and Linux systems.
