David Keefer and Ray Wilson of the U.S. Geological Survey assisted in the post-earthquake reconnaissance efforts and in defining the landslide limits. John Michael and Art Tarr of the U.S. Geological Survey helped construct the digital landslide map. Al Barrows and Pam Irvine of the California Division of Mines and Geology, and Robert Larson of Los Angeles County provided useful information on the location and nature of many landslides triggered by the earthquake.
This extensive database will allow quantitative modeling of the relation between strong ground shaking, landslide susceptibility, and landslide distribution. The area of the greatest landslide concentration currently is undeveloped, but many parts of this area in the Santa Susana Mountains are slated for future dense residential development. We anticipate using the data and modeling results from the Northridge earthquake to produce regional maps of earthquake-induced landslide hazards that can be used to make informed decisions regarding development in the areas most susceptible to seismically triggered landsliding.
