Steel Rebar. Reinforcing bar, or rebar, is a common steel bar that is hot rolled and is used widely in the construction industry, especially for concrete reinforcement.
These flows generally occur during periods of intense rainfall or rapid snow melt. They usually start on steep hillsides as shallow landslides that liquefy and accelerate to speeds that are typically about 10 miles per hour, but can exceed 35 miles per hour. The consistency of debris flows ranges from watery mud to thick, rocky mud that can carry large items such as boulders, trees, and cars.
Volcanic structural collapse in the form of avalanches, rock fall, or landslides can be almost any size ranging from a few loose rocks falling from the crater rim of a volcano to large avalanches such as the one at Socompa Volcano in Chile that covers 500 square kilometers (Francis, 1993).he reason for this is due to energy stored in material within the avalanche. Some large avalanches have been known to carry blocks as large as three kilometers in length, several kilometers from their source. Such avalanches can travel close to 300 km/hr (Francis, 1993)! Landslide is a general term for mass movement.
