Mudslides are made up of of rock,dirt, random debris and also water. They start off slow and then pick up speed and more mud. This takes out trees, cars, and houses. They can occur during any time of the year regardless of weather condition. Earthquakes,volcanic eruptions, changes in water levels, alternate freezing and thawing, and steepening slopes are a few contributing factors of mudslides. =====

Where they occur
Mudslides occur everywhere but mostly by steep slopes and mountains.Usually in wet areas.

Prevention
There is not much people can do to prevent a mudslide, but people can plant trees and carve steps to help preventing mudslides. people living on hills or mountainous areas, especially onesprone to wildfires, earthquakes or heavy rainfall have to be cautious. Walls may also be built but they must be properly designed and regulary maintained.

**Damage Caused by Mudslides **

 * Take out roads
 * Flood houses
 * Take lives-buried by the mud....suffocation
 * Wash away cars, animals and homes
 * Makes rivers break its banks
 * Increase rainfall
 * Leave people with nothing

**Engineering Solutions**

 * Improve drainage-cutting canals in wet areas
 * Reducing the slopes steepness-digging terraces
 * Excavating top of slopes-flatening the tops
 * Making walls to reinforce the bottom of slopes-putting walls around hill to hold dirt back.
