The USGS landslide team monitors and continues to update the hazard map models based on data collected in burn areas. This information improves future models and provides better hazard assessments used by officials for emergency response and decision making. Many of the steep hillsides burned and denuded in California fires repel water rather than soak it in.

A two-day rainstorm from January 26-28, 2021 caused numerous mudslides, debris flows, and other issues along California's coastal Highway 1 through Big Sur. This is Big Creek Bridge, and Big Creek is still murky. Plumes of the muddy runoff are clearly visible in the ocean.

A mudslide near the 2020 Dolan Fire's ignition point chopped through a chunk of California's scenic State Highway 1 in late January.
The Dolan Fire began near Big Sur on August 18th, 2020. It scarred nearly 125,000 acres before being fully contained in December.
