    Geology to unplanned construction: Decoding why Joshimath is sinking

    On Thursday, the Uttarakhand government banned construction work in and around Joshimath over land subsidence that has resulted in cracks in 561 homes there leading to protests by panicked locals.
    Here’s the science behind the subsidence.
    The USDMA study said that the perennial streams, appreciable snow in the upper reaches, and highly weathered gneissic rocks with low cohesive characteristics makes the area prone to landslides.
    This adversely impacted the stability of the slope on which Joshimath town is situated,” the USDMA report said.
    MCT passes below Helang, a little south of Joshimath Town, and juxtaposes with the rocks of Garhwal Group (Joshimath Formation), thereby bringing the town under the impact zone of any tectonic activity on MCT.
    Unplanned construction Hemant Dhyani, environmentalist and member of Supreme Court appointed High Powered committee (HPC) on the Char Dham Project said despite being fully aware of the geological vulnerability of the area, hydroelectric schemes have been sanctioned around Joshimath and Tapovan, including the Vishnugad HE Project.
