Mudflow
Mudflow
Mudflow (pronunciation: /ˈmʌdfləʊ/), also known as a debris flow or lahar, is a type of fast-moving landslide that follows a channel, such as a river. The term originates from the English words "mud" and "flow".
Definition
A mudflow is a rapid movement of a large mass of mud formed from loose soil and water. The flow is usually caused by heavy rainfall or melting snow and can be triggered by an earthquake, volcanic eruption, or human activities such as deforestation.
Characteristics
Mudflows are characterized by their fluid nature and the speed at which they can travel. They can carry large items such as boulders and trees and can bury everything in their path. The speed and destructive power of a mudflow depend on the volume of material, the slope of the terrain, and the amount of water in the flow.
