A video has emerged showing the dramatic moment that tonnes of rock fell from a cliff on the west Dorset coast.

As previously reported, the landslip happened in Seatown.

The video shows an unstable section near the top of the cliff coming down.

It was captured by Lyme Bay RIB Charter - a company offering boat trips along the Jurassic coast.

While rockfalls are a natural part of the erosion process, they have been happening frequently in recent times - and while warning signs are in place at various locations, people have been seen taking unnecessary risks. 

Advice is:

  • Do not take unnecessary risks; stay away from cliff top edges and also the bases of cliffs – rock falls can happen at any time
  • Do not climb or walk over landslide or rock fall debris, especially after wet weather
  • Always pay attention to warning signs; they are there to advise you on how to stay safe
