LANDSLIP Research has conducted two tests in 2020
GSI has been engaged in developing an experimental Regional Landslide Early Warning System (LEWS) based on rainfall thresholds since 2017 through the LANDSLIP project. LANDSLIP research has developed a prototype model based on terrain-specific rainfall thresholds for two test areas in 2020 – Darjeeling and Nilgiris. Landslip is presently in the process of transferring the above instruments of regional LEWS to the National Nodal Agency (GSI) for carrying out a similar effort in several landslide prone states in India.
Landslide warning system to be added by 2022
Since the 2020 monsoon, the GSI has also started issuing daily landslide forecast bulletins during monsoon to the district administration in two pilot areas for testing and evaluation. GSI has taken up R&D activities and ground work for development of regional LEWS in other trial areas like Uttarakhand, Kerala, Sikkim from 2021 onwards and plans to connect five additional states – Himachal Pradesh, Karnataka, Assam, Meghalaya and Mizoram by 2022. There is also a plan. ( landslide warning system)
