Geologic mapping and El Niño:
Landslide and debris-flow susceptibility
maps
Geologists witness the long-term record of many storms when they study deposits at the surface of the Earth; as a result they are especially well-suited to examine the history of El Niño events and make predictions for consequences of future El Niño events. Excessive rainfall and snowfall can trigger floods and mass-sliding of earth, rock, and mud. Geologists can predict about how much rain or snowmelt are needed before destructive floods and landslides occur, so they can make maps that depict locations and the likelihood of various hazardous conditions that might result from El Niño storms.
