This makes the area extremely vulnerable to ever-burgeoning infrastructure and population.<\/span><\/p>\n<p><b>Secondly,<\/b><span style=\"font-weight: 400;\"> the lack of a proper drainage system might have contributed to the sinking of the area. Experts say that unplanned and unauthorized construction has led to the blocking of the natural flow of water, which eventually results in frequent landslides.<\/span><\/p>\n<p><b>Thirdly, <\/b><span style=\"font-weight: 400;\">subsidence might have been triggered by the reactivation of a geographic fault \u2014 defined as a fracture or zone of fractures between two blocks of rock \u2014 where the Indian Plate has pushed under the Eurasian Plate along the Himalayas.<\/span><\/p>\n<p><b>Fourthly,<\/b><span style=\"font-weight: 400;\"> the incident might have occurred because of unplanned construction, over-population, and obstruction of the natural flow of water and hydel power activities.<\/span><\/p>\n<p><b>Fifthly<\/b><span style=\"font-weight: 400;\">, residents have blamed NTPC\u2019s Tapovan Vishnugad Hydro Power Project for the incident.
