Neath Port Talbot Council has said that the latest survey results of the Pantteg landslide in Ystalyfera show the at the failure is “very active” and further instability is likely to occur on a frequent basis.
Residents on Cyfyng Road were evacuated from their properties six months ago following the latest phase of movement which led to the current investigation by Earth Science Partnership (ESP).
ESP has carried out a Lidar survey of the village in the Swansea valley in addition to movement monitoring to create a hazard risk map of the area. Local residents were given the opportunity to see a 3D fly-through model showing the landslip area and other detailed information at a public meeting.
“We have used huge resources and a large amount of public money and have engaged trusted geological experts to give residents in the Pantteg area a greater understanding of the land that surrounds them and which they live on.”
“Earth Science Partnership is now providing residents in the Pantteg area with the most detailed information they possibly can about the risks posed by landslides which have plagued this area going back at least to the 1890s,” said Neath Port Talbot Council leader Rob Jones.
The current phase of work started following ground movements in February 2017 and the residents were evacuated after further movement in June 2017 but the area has experienced stability issues since 1897.
The council has said that slope analysis work on the Cyfyng Road area, quarry inspections and retaining wall strengthening is still ongoing.
