Spot on Hugo......"The problem is that the erosion is not entirely due to sea levels, the problem is coming from the Orme itself. Free flowing water brings out the soil with it and when the cliff dries with that westerly wind, the soil cracks and falls down the cliff"
I dd not realise that the subsidence was so close to St Petrocks, nasty, your photos definitely show the problem needs addressing, sooner than later, perhaps a good use for the toll fee's ?
