Geologic mapping and El Niño in southern California:

Where landslides and debris-flows susceptibility maps are being constructed

The U.S. Geological Survey's Southern California project is using a predictive model for describing areas more prone to damage from landsliding and debris flows. It also is using studies of past damage from El Niño events to sharpen the description of areas prone to possible future damage. The map shows where debris flow maps will be available
