in which year there was a heavy landslide in nainital
Nainital In September 1880 a landslide ('the landslip of 1880') occurred at the north end of the town, burying 151 people. The first known landslide had occurred in 1866, and in 1879 there was a larger one at the same spot, Alma Hill, but "the great slip occurred in the following year, on Saturday 18 September 1880."[8]
Geology of the Alps The Alps arose as a result of the collision of the African and Eurasian tectonic plates, in which the Alpine Tethys, which was formerly in between these continents, disappeared. Enormous stress was exerted on sediments of the Alpine Tethys basin and its Mesozoic and early Cenozoic strata were pushed against the stable Eurasian landmass by the northward-moving African landmass. Most of this occurred during the Oligocene and Miocene epochs. The pressure formed great recumbent folds, or nappes, that rose out of what had become the Alpine Tethys and pushed northward, often breaking and sliding one over the other to form gigantic thrust faults. Crystalline basement rocks, which are exposed in the higher central regions, are the rocks forming Mont Blanc, the Matterhorn, and high peaks in the Pennine Alps and Hohe Tauern (Stampfli & Borel 2004).
