Bygget förstördes i glaciärraset i området 2021 (ESA)

Sprickor kopplas till bygge av ett statligt kraftverk

Bygget av ett stort vattenkraftverk över floden Dhauliganga i Himalaya i norra Indien kan ha förvärrat den redan existerande rasrisken i staden Joshimath. Det säger experter och lokalinvånare enligt den indiska miljöorganisationen Down to earth och The Indian Express.

Sprickorna började dyka upp i staden 2021, men har uppmärksammats av myndigheterna först nu. Geologen SP Sati är en av flera forskare som undersökt marken runt Joshimath efter önskemål från de boende och han säger att bergssluttningarna runt staden är mycket instabila.

En av forskarnas teorier är att den senaste tidens förvärrade sprickor i fastigheter och i marken orsakats av underjordiska tunnlar som byggs kopplat till kraftverket Tapovan Vishnugad.

Kraftverket Tapovan Vishnugad

The Tapovan Vishnugad Hydropower Plant is a 520 MW run-of-river hydroelectric project being constructed on Dhauliganga River in Chamoli District of Uttarakhand, India. The plant is expected to generate over 2.5 TWh of electricity annually.Tapovan Vishnugad is NTPC's second hydro power project since its foray into the sector. The 520 MW run-of-the-river project is situated on river Dhauliganga in Chamoli district of Uttarakhand. Its journey started with NTPC entering into an understanding with the Govt. of Uttarakhand for feasibility study for the project on 31.12.2002 and then signing the Implementation Agreement on 23.06.2004. Currently, it is in advanced stage of construction with around 70% of the implementation completed. The project has set its target for commissioning in first half on FY 2020-21. The Foundation Stone of TVHPP was laid by Shri P M Saeed, the then Union Minister for Power, on 14 February 2005 in the august presence of Shri ND Tiwari, CM of Uttarakhand. The power plant is located downstream on the Alaknanda River and will contain four 130 MW Pelton turbine-generators. The barrage is being constructed across the Dhauliganga River and has a catchment area of 3,100 km2. BHEL was awarded the contract to supply four 130MW Pelton type turbines for the Tapovan Vishnugad hydroelectric power project. The contractual scope also included the testing, commissioning and operation of the generators, switchgear and excitation system. The project construction was awarded to a joint venture of Larsen & Toubro and Austria-based Alpine Mayreder Bau GmbH, but the contract was terminated in 2014 as geological constraints delayed tunnel construction. The tunnel project was then awarded to Hindustan Construction Company in 2016

Joshimath, also known as Jyotirmath, is a city and a municipal board in Chamoli District in the Indian state of Uttarakhand. Located at a height of 6150 feet (1875 m), it is a gateway to several Himalayan mountain climbing expeditions, trekking trails and pilgrim centres like Badrinath. It is home to one of the four cardinal pīthas established by Adi Shankara. Since 7 February 2021, the area was severely affected by the 2021 Uttarakhand flood and its aftermath.
