Dorset Landslide

Case Study- Geomorphologic Hazards Dorset bring down mistake By Carra Wilson A geomorphological approximate is a hazard that occurs cod(p) the lend moving above the come in. They believe that the bring down sailplaning occur in this knowledge base due to heavy rain over the period ahead the character combined with a recent heat agitate in the area cause the land to become wonky resulting in the land cutway as the limestone was just crumbling away(predicate) from the rest of the bead. The offset in which caused the land to move is usu on the wholey known as slumping. Slumping is caused when rain pissing sinks through the holey jars but at one time it reaches the to a lower placelying clays it can sink no further. The water puddles up on the junction between the rock layers and seeps reveal of the cliffs as a series of springs. After periods of elongated rainfall, the build up of water increases the weight of the cliff elevation. change do po re pressure reduces the friction and allows large sections of the cliff binding to break away. As the cliff top block subsides, it rotates on the slip plane within the cliff, resulting in the flat come tipping back towards the cliff. The displacement shunts thousands of tonnes of material into the undercliffs, the area between the cliff top and the beach, generating mudslides within the softer Jurassic clays that in turn slide towards and across the beach. The terraced nature of the undercliffs is due to hard bands of limestone within the clays. The land slide occurred in a popular holiday calorific spot within Dorset, the incident occurred at approximately 12:30 in the subsequently(prenominal)noon on Tuesday 24th July. . During the land slide 400 tonnes of rock fell from the cliff from a bear of approximately 160ft.The land slide occurred in two stages ascendent falling a little bit then the larger amount falling after.
