Areas ravaged by wildfire have increased susceptibility to mudslides and debris flows during heavy rains.

high
hazard
Burned vegetation and altered soil properties reduce slope stability and increase runoff, elevating post-fire landslide and debris-flow risk when heavy precipitation occurs.
Land areas recently burned by wildfires are more susceptible to mudslides, debris flows, and erosion during subsequent heavy rainfall or thunderstorms because loss of vegetation and altered soil properties reduce slope stability.

Explains how wildfire burn scars change landscape vulnerability to post-fire runoff and mass-wasting events.
Areas recently affected by wildfires are at increased risk of mudslides and debris flows during subsequent thunderstorms and heavy rainfall.

high
hazard
Loss of vegetation and altered soil conditions after wildfires make slopes more susceptible to rapid runoff and slope failure during heavy precipitation.
Wildfires can remove vegetation from hillsides, which reduces soil stability and increases the likelihood of debris flows, mudslides, and landslides during subsequent heavy rainfall.
