Noklak landslide threatens 1.84 sq. km, one-fifth of town's population
This is a scientific study published in the journal 'Disaster & Development' by researchers from Nagaland University that analyzes the geomechanical causes of the Noklak landslide in Tuensang District, Nagaland. It matters to citizens as it provides technical evidence regarding the instability of the slope affecting the town's infrastructure and population.
Residents of Noklak town in Tuensang District, Nagaland; researchers from the Department of Geology at Nagaland University; and the public affected by the landslide covering 1.84 sq. km.
- The study identifies the Noklak landslide as a complex instability affecting 1.84 sq. km, threatening nearly one-fifth of the town's population and the route to the International Trade Centre at Pangsha.
- Kinematic analysis of 1,195 joint attitudes indicates both planar and wedge type failures, with several micro-slips and an absence of firm bedding.
- Rock Mass Rating (RMR) and Point Load Test (PLT) data indicate poor rock quality and low strength values for the rocks in the area.
- Slope Mass Rating (SMR) values for the slope fall in Class IV, which is described as 'Poor' rock and 'Unstable' stability.
- The landslide initially started in 1980 and was reactivated in 2004, with subsequent failures in succeeding years.
