The Geological Survey of India (GSI) on Thursday gave the Uttarakhand Government a comprehensive report based on a survey of the areas hit by disaster in the State in June last year.

The survey, which was conducted by 21 scientists from across the country over a period of six months, is based on the study of the disaster-hit districts of Rudraprayag, Chamoli, Uttarkashi, Pithoragarh, and Bageshwar.

The unprecedented rainfall in June resulted in sinking and erosion of land as well as landslips across the State.

Immediately after the deluge, a GSI team visited Kedarnath, which is in Rudraprayag district. Director of GSI’s State unit Dr. V. K. Sharma said: “We have suggested that the boulders deposited in the Kedarnath temple premises be removed in a scientific manner.” The course of the Mandakini river was diverted due to the disaster. Dr Sharma said: “The Mandakini should be channelised to its original course.”
