Mudflow

Mudflow-this is a dangerous natural phenomenon inherent in some mountainous areas of our country, a stream with a very high concentration of mineral particles, stones and debris, which suddenly appears in the basins of small mountain rivers and dry ravines. Originating high in the mountains, it begins to move rapidly along the bottom of a steep mountain gorge. Capturing new masses of stone fragments, he becomes so powerful and unstoppable.

Causes of occurrence. Intense and long showers. Rapid melting of glaciers or seasonal snow cover. Due to the collapse of large amounts of friable material into the channel. Destruction of the grass cover. Earthquakes and volcanoes.

They travel tens of kilometers and carry hundreds of thousands and even millions of cubic meters of solid material from the mountains. Occur in the mountains of the Caucasus, Asia, Siberia, the Alps, the Carpathians and the Cordilleras.
