Walkers are warned to stay away from the edge of Seven Sisters after further cliff fall at the beauty spot this week.
This comes as chalk cliffs at nearby Seaford Head also suffered with erosion on Sunday (October 14).

A statement on the Seven Sisters Country Park website said: "Recent cliff falls serve as a useful reminder that chalk cliffs are naturally unstable and visitors should stay well away from the edge and the base of any cliffs.
"While we would encourage people to enjoy the beautiful coastline of East Sussex, we would remind visitors that you do have a duty of care and responsibility for your own safety."
The erosion at the world-famous white cliffs is caused either by rough seas or heavy rainfall, according to the National Trust. Water passes through the chalk when it lands on the surface and then freezes as temperatures drop. The water then expands and cracks the chalk, causing the cliffs to erode from the top, the Trust said.
After a cliff fall at Seaford Head, Newhaven Coastguard said: “There is the possibility of more falls along the south coast after this period of heavy rain which is increasing the risk of cliff instability and it makes cliff falls more likely.
“People should give the cliff edges a very wide berth and not to get too close to the top of cliff edges or approach the base of cliffs either.”
