Mudslides –– also known as debris flows –– are a fast-moving type of landslide. They are comprised of masses of rock, earth, and/or debris rushing down a slope. Mudslides usually happen on steep slopes when the soil has become saturated.

How are mudflows caused?

Mudslides occur when a large amount of water causes the rapid erosion of soil on a steep slope. Rapid snowmelt at the top of a mountain or a period of intense rainfall can trigger a mudslide, as the great volume of water mixes with soil and causes it to liquefy and move downhill.

How does a mudslide affect the atmosphere?

Mudslides create a favorable litter quality and quantity, soil moisture, and temperature condition for a promoted net nitrogen mineralization and create a larger nitrate gradient between the aerobic layer and the underlain anaerobic layer, where it is denitrified into gaseous state and lost to the atmosphere.

How do mudslides affect the Earth?
