What is a landslide susceptibility map?

Welcome to CoreFacts, where we're always short on time and big on science. I'm Steve Sobieszczyk. Let's get right to it, today's question is:

What is a landslide susceptibility map?

This type of maps ranks slope stability of an area into categories that range from stable to unstable. Susceptibility maps show where landslides may form. Many susceptibility maps use a color scheme that relates warm colors (red, orange, and yellow) to unstable and marginally unstable areas and cool colors (blue and green) to stable areas.

And now you know. Join us again tomorrow as we'll give you yet another new CoreFact.
