(N.Morgan) A huge section of chalk cliff collapsed at Birling Gap in East Sussex and plunged into the ocean, today. As you can see, there were onlookers, who seem to be unaware of what is going on. This is the moment a stretch of grass-topped cliff toppled into the sea in a cloud of rubble and dust after the winter’s savage storms caused seven years of erosion in just three months. To the shock of stunned bystanders sat on a wall just meters away the chunks of cliff top broke away from the cliff face at Birling Gap, on the East Sussex Coast and plunged onto the beach below today.
