Goals
USGS Landslide Research in Oregon

• Advance scientific understanding of important
  landslide processes and hazards,
• Develop methods and techniques that are
  applicable in Oregon and transferable elsewhere,
• Provide information that decision makers and the
  general public can use to reduce
  landslide-related damages, losses, and fatalities

• Selected urban areas and transportation corridors
  
• Sediment entrainment by rapidly moving landslides
• Role of hillslope hydrology in landslide
  occurrence and reactivation
• Rainfall intensity and antecedent soil wetness
  for occurrence of landslides
• Mechanisms of coastal landslides
