KOLKATA: The Geological Survey of India (GSI) has started systematic mapping of all landslide prone areas in the country to avert damages, its Director General Dinesh Gupta said on Thursday.
The GSI has identified parts of Uttarakhand, Himachal Pradesh, Darjeeling area of West Bengal, Sikkim, Jammu and Kashmir and some portions of South India comprising hills – and undertaken systematic mapping of which area is prone to landslides, Gupta told reporters here.
“Any slight movement will be recorded, fed into the system and used to warn state authorities about any possible occurance (of landslide),” he said at the meet called to highlight GSI’s activities.
Data pertaining to 1.71 sq km area was already available and all one would have to do was to type the location and see the result on map, Gupta said.
He said that by 2021, the entire data feed process is expected to be completed.
On early warning system for earthquakes, he said there is no technology to forecast it but GSI is cautioning people about which area is more prone to quakes, and which kinds of building needed to be built.
“We are studying sub-surface and it is a continuous process,” he said.
He said GSI is giving greater thrust on mineral exploration to give more auctionable blocks to respective state governments.
