Here is the coastguard photo of the rotational slump at Red Cliff, Marloes, on the west coast of Pembrokeshire --SM 788071 to SM 790069. A classic of its kind! This illustrates how coastlines evolve -- with slow and incremental change maybe for centuries or millennia, and every now and then a catastrophic and instantaneous change of vast proportions, triggered by over-sturation of sediments on a slope, or an earth tremor, or an extreme storm event.
The landslide occurred around 21st November. Luckily nobody was hurt. Must get over there to have a look........
