North Wales Police tweeted that they were dealing with a huge landslide on Nefyn’s coastline near Pwllheli. It is believed to have happened between 10.30 and 11.00 this morning. A police spokesperson said: “We are currently dealing with an incident involving a large landslide on the beach at Nefyn.
“We are aware of people gathering to take photographs – the public are advised to avoid the area until further notice, whilst emergency services and utility companies make the area safe.”
A subsequent tweet said: “Gardens of residential properties are affected – please avoid the beach area.”
Aerial photos show parts of garden being dragged into the sea. There are houses near the edge of the affected area.
There are no reports of any casualties and police have set up cordons in the area. The Welsh Ambulance Service have confirmed that they were not called to the scene.

“I don’t think anyone was on the beach. We had gone down there about half an hour after it happened. It is a good 40m wide, but it is hard to tell.”
Experts say that the recent warm days and cold nights have caused existing cracks in the mountainside to get bigger and parts of the cliff face fell away.
Local residents in North Wales say there have been some smaller landslips along the coastline in recent months. A rock fall near the Great Orme’s head in Llandudno has led to street closures.
A massive landslip on the Jurassic Coast last week saw 4,000 tonnes of cliff plummet onto a beach. Some boulders were the size of cars and crashed 430ft to the ground. The rockfall was also blamed on recent weather.
