Click on icons and lines, and an informational bubble will pop up. The star icons represent areas considered by the U.S. Geological Survey to be at risk for mudslides in the worst-case scenario. Under this scenario, a rainstorm would last 12 hours, striking when debris-retention basins are already full. Such a storm occurs about once every two years. Mudslides can also occur with less rain when basins are not full. The red fire perimeter shows the boundaries of previous fires.
