Happisburgh tree-shaped cliff collapse captured in drone footage
Drone footage has shown the scale of a tree-shaped cliff collapse that appeared on the Norfolk coast.
An expert believed the deep scouring at Happisburgh was caused by water running off a field and cascading over the cliff after heavy rain, rather than erosion caused by the waves.
Geologist Martin Warren said: "This is, I think, just a temporary phenomenon resulting from the unfortunate way in which the field was ploughed.
"I don't think water's channelled in that direction the way it was and it was probably a particularly downpour that caused the problem in the first place."
