Mudslide redirects here, it is also the name of a cocktail.

A mudflow or mudslide is the most rapid (up to 80 km/h / 50 mph) and fluid type of downhill mass wasting. It is a rapid movement of a large mass of mud formed from loose earth and water. Similar terms are debris flow (e.g. in high mountains), mudslide (not very liquid) lahars and mud stream (e.g. from volcanoes; see also lahar).

However, these terms show a broad variety

• in water content (from loamy mud up to almost liquid),
• in material (wet soil, sandy sediments and/or silt, dirt, rock debris, volcanic ash, small plants and even trees)
• and in length, total mass and velocity.
