National Collaboration

MoU between GSI and NRSC on landslide studies

A framework MoU was signed between NRSC and GSI on 20th December 2013 at central headquarters GSI, Kolkata regarding event-based landslide inventory mapping and landslide susceptibility/hazard zonation in the landslide vulnerable areas of India. Under this MoU, a project on landslide hazard and risk mapping of parts of Mandakini valley (Kedarnath area) is being taken up as a two-year programme commencing from 1 April 2014. By the end of March 2015, landslide susceptibility analyses using multi-temporal landslide inventory dataset were completed.

MoU between GSI and DTRL on landslide studies

A Memorandum of Understanding (MoU) was signed on 5th September 2014 between Defense Terrain Research Laboratory (DTRL), DRDO, Ministry of Defense, Metcalfe House, Delhi and Geological Survey of India (GSI), Ministry of Mines, 27 J.L. Nehru Road, Kolkata on "Development of Instrumentation and Monitoring of Landslides for Early Warning System in India" at GSI, Central Headquater, Kolkata. This MoU aimed to achieve the objectives to develop technology for an Early Warning System of a landslide based on instrumentation and empirical relation of rainfall and ground displacement. The project will also lead to development of a Standard Operating Procedure (SOP) for instrument based landslide monitoring. The necessity of having R&D on landslide monitoring and development of Early Warning System was felt aftermath of Uttarakhand Disaster of June 2013. With DTRL having expertise in instrument based monitoring of landslide and GSI having expertise in geological/geotechnical modeling of landslides, this MoU forms a good platform for combining both the knowhow to develop a real time landslide warning system in India.

International Collaboration

GSI-NRSC-ITC collaboration on landslides

A joint collaboration among GSI, NRSC and ITC, The Netherlands was initiated in the year 2007 to carry out advanced research in landslide domain. As part of this programme, two researchers from GSI focused their work on the development of innovative landslide hazard and risk management methods. One researcher from NRSC focused on the creation of landslides inventory from high resolution IRS satellite data using automatic image classification methods. The GSI's work on landslide hazard and risk analysis in Darjeeling Himalaya and Nilgiri hills of Western Ghats resulted in more than 15 publications in International peer-reviewed Journals.

GSI-NRCan, Canada collaboration on landslides

In order to evolve a methodology and to have a better understanding of the landslide problem, an attempt have been made for the first time by the Geological Survey of India and Geological Survey of Canada to develop an early warning system by installing instruments in slide area and monitor their movement through real time analysis between 2003 and 2008. To fulfill this objective a memorandum has been signed between Government of India and Government of Canada for monitoring/mitigation of landslides at selected sites in India in 2008. The pilot landslide sites selected for this Indo-Canadian Collaborative program on landslide mitigation are 9 mile Slide in Sikkim, Hospital Slide in Nilgiris and Surbee Slide in Mussorie area.

As part of Indo-Canadian collaboration under Landslide mitigation programme w.e.f 26.03.08 to 15.05.08 the training schedule divided into two phases: 1st Phase (26.05.08-09.04.08) - A GSI team comprises of three Directors (S/Shri D. N. Bhattacharya, V. Balachandran and R. K. Awasthy) and three field geologists (S/Shri C. Thanavelu, Niroj K. Sarkar and Pankaj Kumar) were exposed to the landslide problems existing in Canada, and were taken to the landslide sites and also shown the mitigation measures taken. Also during the first phase there had been several deliberations and discussions with the companies like RST, DGSI, TRE and Roc Test mainly dealing with the instruments which can be used in real time monitoring of landslides. 2nd Phase (11.04.08-15.05.08) - three visiting geologists were given training on Map Server training at DM solutions, Ottawa, Geomatica 10.1 at PCI Geomatics, Gatineau, Quebec and Geostudio 2007 modules at Geoslope International, Calgary to have much for better understanding of the technology and techniques being used by them in dealing with landslide studies, in particular.

In 2012, the umbrella MoU between Natural Resources, Canada and MoM/ GSI was extended for another 5-year Term till 2017 and an attempt is being initiated by both the countries to carry out/ continue landslide monitoring and early warning studies in some selected landslide sites in India using satellite-based (using RADARSAT 2 and RISAT II data) SAR Interfermetry techniques. For this, soon a joint site visit by the Canadian and GSI experts will be held (expected in November 2015) to fix the modalities of studies at two selected landslide sites (14th Mile/ Gayabari landslide, Darjeeling District, West Bengal and Hospital landslide, Conoor, Tamil Nadu). NRCan has already supplied five corner reflectors to GSI for this purpose.
