Causes of the rapid erosion:

Weather —> winter storms (stronger waves eroding cliff, rain causing increased cliff runoff leading to slumping)
Waves —> dominant waves and largest fetch from NE, destructive waves attack cliff, carry away clay in solution and take it S, where it’s deposited in the Humbery estuary (Spurn Head)
Geology —> chalk and boulder clay. Clay is very soft (easily eroded) and formed bay of Holderness, chalk not that much and formed Flamborough Heads
Interfering with natural processes (e.g. groynes in a Mappleton prevent LSD, so less material S)
Global Warming + other short-term changes in climate (partly human) —> sea level rise, more erosion from abrasion, solution, hydraulic action and solution
