Why it matters

What Landslide or Mudslide would mean for you

Three numbers decide how important Landslide or Mudslide is to your preparedness planning. Impact and Likelihood are general baselines. Vulnerability depends on how prepared you are for this threat.

ImpactModerate6/9

NegligibleCatastrophic

Where the ground is at risk a slide can destroy a home in seconds and bury those inside - a high Impact, though confined to specific terrain.

LikelihoodRare2/9

RareFrequent

Very terrain- and rainfall-specific, so the Likelihood is low for most and meaningful only on vulnerable slopes.
