Question

How does a wildfire turn into a mudslide?

Answer 1

Fire burns hot and destroys the root systems holding a slope in place, which then fails after a heavy rain following the fire. Additionally no water is intercepted by the trees and it all infiltrates into the soil.

Answer 2

All the water required to put out the fire, can cause a mudslide if in fact somewhere within that fire there was any loose or unstable ground (earth). It can cause a mudslide.

Answer 3

Here in California, we get this alot!  The fire destroys all the natural vegetation on the hillside (trees, bushes, etc).  When the rain comes, there is nothing holding the hillside, so it slides down.
