The National Building Research Organisation (NBRO) has identified instability in the upper slope and the reactivation of an old landslide as the main causes of recent landslide incidents in the Kadugannawa area along the Kandy-Colombo road.
NBRO Kandy District Chief Geologist Chathuri Subasinghe said preliminary geological investigations had been completed and that work to stabilise the affected locations had already commenced.
She said rockfalls and slope instability had recently been observed in the area. Following the preliminary surveys, the final report was submitted to the Yatinuwara Divisional Secretary yesterday.
According to Subasinghe, investigators found evidence of instability in the upper slope area, along with signs indicating that the location is part of an area affected by an older landslide.
To ensure the safety and stability of the road, the NBRO has recommended a detailed investigation and the implementation of necessary mitigation measures.
She added that the report had also been forwarded to the organisation’s head office to speed up the process, with the aim of carrying out the recommended work within the next week.
