Plotting multiple fault representations: Applications for National Seismic Hazard Model 2023 update (NSHM-faultmaps)

The National Seismic Hazard Model (NSHM) utilizes a fault sections database (FSD) throughout the model workflow. Working towards a 2023 NSHM release, the NSHM23 FSD encompasses a major update with the addition of new fault sections, as well as the revision of existing fault sections from prior FSD (2014). The additions and revisions were largely based on the U.S. Geological Survey's Quaternary Faults and Folds Database (QFFD). The nshm-faultmaps.ipynb Jupyter Notebook (Python code) provides users with a visual, side-by-side comparison of fault representations from the QFFD, NSHM14 FSD and NSHM23 FSD. The code downloads the fault sections databases to the user's computer and plots maps of each fault based on the user's preferences.
