Mailboxes caught in a mudflow following the May 1980 Mount St. Helens volcanic eruption. A mudflow, also known as mudslide or mud flow, is a form of mass wasting involving fast-moving flow of debris and dirt that has become liquified by the addition of water. [1] Such flows can move at speeds ranging from 3 meters/minute to 5 meters/second. [2]
Media reports often use the term mudflow to describe debris flows, but true mudflows are composed mostly of grains smaller than sand. On Earth's land surface, mudflows are far less common than debris flows. However, underwater mudflows are prevalent on submarine continental margins, where they may spawn turbidity currents.
The knowledge of the landslide frequency is a fundamental element for any kind of probabilistic evaluation. Furthermore, the evaluation of the age of the landslide permits to correlate the trigger to specific conditions, as earthquakes or periods of intense rains. It is possible that phenomena could be occurred in past geological times, under ...
Officials said 16 homes were damaged or destroyed after a mudslide Sept. 12. One woman was found dead in her home. In San Bernardino mountains, residents hit by devastating mudslide fear more to come
