Overview
- Anglesey Council closed a section of the coastal path above Porth Swtan and told visitors to avoid the area following Wednesday’s major landslip.
- Footage filmed by local resident Huwie John Morris showed walkers fleeing as tonnes of rock and soil crashed onto the beach at about 11am.
- Locals say the collapse was the fourth significant rockfall in under two weeks after stormy weather and persistent winter rain.
- GeoMôn explained that the cliffs are made of fragile volcanic tuffs that lack strength, contributing to long-running instability.
- Natural Resources Wales projects significant land loss at the site, and current shoreline policy rejects hard defences in favor of potential managed realignment.
