NBRO warns of continued rockfall risk in Kadugannawa as unstable rocks remain
Summarised by AI from 2 articles
The National Building Research Organisation (NBRO) warned on 11 November that the risk of rockfalls persists in Kadugannawa following an incident on 10 November.
NBRO Senior Geologist Dr. Wasantha Senadeera said unstable rocks remain above the site and could fall at any time. He also highlighted danger along the railway line in the Kadigamuwa area.
Dr. Senadeera explained that predicting landslides and rockfalls is difficult because localised rainfall often evades Department of Meteorology forecasts, with rain gauges spaced six to 10 kilometres apart.
He noted that a rain gauge at Kurukuttala (reported as Guruguththala by Thamilan) School, one kilometre away, recorded no significant rain despite localised rainfall triggering the rockfall. He urged residents in vulnerable areas to remain vigilant.
