An example of calibration and validation of CoSMoS-COAST using historical satellite-derived shoreline data. The figure shows the extent of the CoSMoS-COAST U.S. South Atlantic Coast model transects (panel A—in green) with a zoomed in section of Cape Hatteras, North Carolina (panel B), which shows a close-up of the 50 m transect spacing (green lines).

North-to-south (N2S) rupture simulations with oblique (−45°; panels a–d) and left-lateral (0°; panels e–h) normal fault (NF) pre-stress. In the left column (panels a, b, e, and f), the San Andreas (SSAF) ends at the intersection with the NF, while in the right column (panels c, d, g, and h), the San Andreas (SSAF-EXT) “extends” south of the SSAF-NF intersection.

Following the partial collapse of the Santa Cruz Municipal Wharf during January 2025 storms, the USGS Pacific Coastal and Marine Science Center was requested to help map seafloor debris by NOAA’s Monterey Bay National Marine Sanctuary.

Examples of environmental contamination risk reduction due to decreased coastal flooding provided by coral reef restoration in Florida. Adapted from the study Coral reef restoration can reduce coastal contamination and pollution hazards.
