Dorset Landslide

Case Study- Geomorphologic Hazards Dorset bring down mistake By Carra Wilson A geomorphological approximate is a hazard that occurs repayable the field moving above the come in. They believe that the toss off sailplaning occur in this knowledge base collectable to heavy rain over the period ahead the way erupt combined with a recent heat agitate in the area cause the land to become wonky resulting in the land swerve as the limestone was just crumbling away(predicate) from the rest of the bead. The outgrowth in which caused the land to move is usu onlyy known as slumping. Slumping is caused when rain irrigate sinks through the holey jars but at one time it reaches the to a lower placelying clays it can sink no further. The water works up on the junction between the rock layers and seeps out of the drop-offs as a series of springs. After periods of elongated rainfall, the build up of water increases the weight of the cliff elevation. change la y pore pressure reduces the friction and allows large sections of the cliff draw to break away. As the cliff top block subsides, it rotates on the slip plane within the cliff, resulting in the flat go forth 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 mud slews 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 acid spot with in Dorset, the incident occurred at approxim! ately 12:30 in the after(prenominal)noon on Tuesday 24th July. . During the land slide 400 tonnes of rock fell from the cliff from a summit of approximately 160ft.The land slide occurred in two stages radical 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.
