The massive crack splits the land in two on the famous Jurassic Coast in Dorset.
The resulting crevasse measures about 250 yards long, up to 3ft wide and 4ft deep on April 12, 2016.
Thousands of tonnes of earth have given way and will continue to slip away, changing the landscape of the renowned coastline.
It is unknown when the cliff will fall down on the beach, but walkers and tourists are now being warned to steer clear of the chasm.
This gigantic landslip was caused by heavy rainfall in the last few months.
Fossil hunters and beachgoers are also being warned as the crack will mean extra clay and mud on the shore below the cliff.
As if an earthquake had struck.
The thing is that this geological process is all part of a progressive evolution of the coastline.
If hundreds of thousands of tonnes of rock have moved there is an increased risk of rock falls and mud that will spill out onto the beach and create a danger.
The soil is very unstable right now so keep away.
