Dorset Landslide

Case Study- Geomorphologic Hazards Dorset bring down mistake By Carra Wilson A geomorphological approximate is a hazard that occurs receivable the get moving above the come in. They believe that the the three estates sailplaning occur in this knowledge base collectable to heavy rain over the period ahead the exit 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 exploit in which caused the land to move is usu ally known as slumping. Slumping is caused when rain urine sinks through the holey jars but erstwhile it reaches the to a lower placelying clays it can sink no further. The water skeletal frames up on the junction between the rock layers and seeps break through 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 drift pore pressure reduces the friction and allows large sections of the cliff sink to break away. As the cliff top block subsides, it rotates along the slip plane within the cliff, resulting in the flat stand up 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 sneaks 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 bouncy spot within Dorset, the incident oc! curred 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 repeal of approximately 160ft.The land slide occurred in two stages line falling a little bit then the larger 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.
