The Geological Survey of India is to develop a digital database of landslides in West Bengal’s Darjeeling hills where slope failures claimed the lives of at least 40 people at the end of June.
At a press conference, GSI geohazards research and management officer Saibal Ghosh said that work on the mapping was already underway and the GIS-enabled maps would be available next year.
According to Ghosh, the region’s geology makes it prone to landslide but “man-made interference sometimes aggravates the situation locally”.
GSI has said that the survey team will categorise the landslides by looking at the dimensions, geology, geomorphology and triggers. Ghosh added that the mapping will include rainfall intensity data.
