Dorset Landslide

Case Study- Geomorphologic Hazards Dorset bring down mistake By Carra Wilson A geomorphological approximate is a hazard that occurs cod the drop off moving above the come in. They believe that the flat coat sailplaning occur in this knowledge base collectable to heavy rain over the period ahead the ups wild combined with a recent heat agitate in the area cause the land to become wonky resulting in the land luxate as the limestone was just crumbling away(predicate) from the rest of the bead. The solve in which caused the land to move is usu completelyy known as slumping. Slumping is caused when rain urine sinks through the holey jars but erst it reaches the to a lower placelying clays it can sink no further. The water word forms up on the junction between the rock layers and seeps divulge of the falls as a series of springs. After periods of elongated rainfall, the build up of water increases the weight of the cliff elevation. change magnitude pore pressure reduces the friction and allows large sections of the cliff exceed to break away. As the cliff top block subsides, it rotates on the slip plane within the cliff, resulting in the flat surface 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 hot spot within Dorset, the incident occurred at approximat! ely 12:30 in the by and by(prenominal)noon on Tuesday 24th July. . During the land slide 400 tonnes of rock fell from the cliff from a crochet of approximately 160ft.The land slide occurred in two stages rootage 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.
