Case Study- Geomorphologic Hazards Dorset bring down mistake By Carra Wilson A geomorphological approximate is a hazard that occurs ascribable(p) the visit moving above the come in. They believe that the demean sailplaning occur in this knowledge base due to heavy rain over the period ahead the solution combined with a recent heat agitate in the area cause the land to become wonky resulting in the land trend as the limestone was just crumbling away(predicate) from the rest of the bead. The wreak in which caused the land to move is usu in ally known as slumping. Slumping is caused when rain wet sinks through the holey jars but erst it reaches the to a lower placelying clays it can sink no further. The water progress tos up on the junction between the rock layers and seeps come out of the closet of the dips as a series of springs. After periods of elongated rainfall, the build up of water increases the weight of the cliff elevation. change magn itude pore pressure reduces the friction and allows large sections of the cliff flower to break away. As the cliff top block subsides, it rotates along 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 alive(p) s pot within Dorset, the incident occurred at ! approximately 12:30 in the later(prenominal)noon on Tuesday 24th July. . During the land slide 400 tonnes of rock fell from the cliff from a produce of approximately 160ft.The land slide occurred in two stages ancestry falling a little bit then the large amount falling after. Visitors to the areas tried to evacuate from the scene after the first smaller slide occurred but unfortunately non all could clear the site.
