A “significant landslip” has affected beachfront properties and prompted safety warnings to coastal path walkers.
Council officials said there was a risk of more “earth falling as water continues to flow down the side” of the private land at Nefyn, Llyn Peninsula.
“We are aware that a number of private properties have been affected, but fortunately they were unoccupied at the time,” said Cyngor Gwynedd.
Nefyn town council chairwoman Mared Llywelyn said the floors of some of the properties had collapsed with the wider community “very worried” as it followed other landslips affecting nearby public paths over the last week.
“These landslides are happening more frequently now,” she said.
“Last year we had extreme storms, and this year it’s just seems that it’s getting wetter and wetter.
She said one path linking Nefyn with Morfa Nefyn which had been widened and resurfaced has had to close after a “chunk” was lost in a landslip.
“We really need to be thinking seriously about the future of our coastal paths in the midst of this climate emergency,” she added.
Cyngor Gwynedd said council staff visited the landslip site on Friday to assess the situation, and had informed the Coastguard.
“As a precautionary measure a section of the coastline, in front of the affected area, has been cordoned off,” said the council.
“We would urge members of the public to take extra care when walking near cliff edges and along the coastline, as the land is more prone to slippages following prolonged periods of heavy rainfall.”
