Location

Lleyn Peninsula

Cause

At Nefyn there is a sea cliff formed from sediments left behind as icesheets and glaciers melted towards the end of the Ice Age.

Animation

Press continue to see the processes causing the landslide at work.

Conclusion

  • Present day OS maps look very similar to those of 1889 with very little coastal erosion [0.03m/year].
  • There is little evidence of the sea undercutting the vegetated cliffs and making them steeper. There is a sea wall protecting the area.
  • August 2000 to February 2001 was one of the wettest on record – rainfall was one and a half times more than the average.
The very wet weather increasing water in the ground was the trigger to the landslide.
