According to official sources here today, the reports of six district towns of Phek, Zunheboto, Mokokchung, Wokha, Kohima and Dimapur, have been taken up for geological hazard studies during 2009-10 and 2010-11 as the towns are prone to landslides and under threat by geo-hazards like earthquakes, water contamination and except Dimapur, which is annually affected by Dhansiri river flood.
The Department of Geology and Mining had placed its final report under compilation with suggestion and recommendation, including remedial measures for implementation, the report stated.
The Director of Geology and Mining H K Chishi, in his report, said the department has made a major contribution towards landslide studies along NH-29 section by using suitable scientific remedial measures for landslide mitigation.
He said NH-29, being the lifeline of the people connecting Dimapur and Kohima, runs through highly landslide prone areas and the department had carried out a project ‘Landslide Hazard Zonation and Disaster Management and Mitigation plan using Remote Sensing (RS) and Geographic Information System (GIS)’, a case study along the highway during 2009-2011 under the state earmarked programme.
Detailed landslide inventory map by collecting all existing information and current data on landslide was also generated for the first time, including preliminary investigation of major slides along NH-29 of Dimapur-Kohima section for understanding and suggestion of remedial plans.
Mr Chishi further said the present report would act as a useful tool for the planners, administration or other decision makers to have quick appraisal regarding the relative stability of a given area utilised. The reports could also be used by road and building construction agencies including research and development agencies, he said. (UNI)
