Why houses and roads in Uttarakhand’s Joshimath have developed cracks?
The land in Joshimath is sinking due to a phenomenon called land subsidence. It refers to the vertical sinking of land in a region. It consists of the Earth’s surface moving downwards vertically and involves little or no movement horizontally. The reason behind subsidence can be both natural causes or human actions.
There are various processes that can lead to land sinking through subsidence. These include:
- The dissolution of carbonate rock lying underneath by groundwater,
- Sediments compacting gradually
- Fluid lava withdrawing from underneath a solidified rock crust
- Mining activity
- Pumping of fluids like groundwater or fuel from under the surface
- Tectonic forces warping Earth’s crust (known as tectonic subsidence)
3000 people from 576 houses have been impacted due to the subsidence. Uttarakhand Chief Minister Pushkar Singh Dhami has assured that necessary actions will be undertaken to save the residents in the district. He is set to visit the district to assess the situation.
"The people of Joshimath are worried about the future of the city," said one resident Madhavi Sati, who is also the ex-Municipal President of Joshimath. She said that there’s no other choice but to live in the ruined house.
