The coast is unstable because there are numerous
situations where porous strata, principally the
Chalk and Upper Greensand, lie over impermeable
clays.
Black Ven between Lyme Regis and Charmouth. Upper
Greensand lies over Lower Jurassic clays. The
largest coastal mudflow in Europe took place here
in the winter of 1958/9
