LANDSLIDES AND DEBRIS FLOWS
Debris flows are rapidly moving, extremely destructive landslides. They can easily travel a mile or more, depending on the terrain. They typically contain boulders and logs transported in a fast-moving soil and water slurry down steep hillsides and through narrow canyons. A debris flow moves faster than a person can run.
Throughout the rainy season, the National Weather Service highlights the potential for debris flows and landslides as part of a flood watch, for areas included in the flood watch.
Some areas are especially hazardous. People, buildings and roads located below steep slopes in canyons and near the mouths of canyons may be at serious risk. The most dangerous places include:

PREPARING FOR LANDSLIDES
Knowing in advance where danger areas around your home might be is the first step in preparing for landslides. Learn more with:
Statewide Landslide Information Database for Oregon (SLIDO): Places where landslides have occurred in the past are at risk. The SLIDO database compiles information on known historic and mapped landslides.
