A preliminary assessment report of the Geological Survey of India (GSI) pointed out that the recent landslide at the Tupul Railway Station in Noney district of Manipur that claimed several lives was caused by an extensive and unprotected slope cut for the construction of the 110-km Imphal-Jiribam railway project.
The area where the landslide occurred is a ‘highly susceptible zone’ as per the National Landslide Susceptibility Mapping (NLSM) of 2019, said the report.
Some other factors that triggered the landslides include dumping of debris which limited the normal water flow of the Ijai river, dumping of unconsolidated materials used for temporary constructions and improper hillside drainage along the slope, the report noted.
