Joshimath Sinking News: Difficulties are not reducing in Joshimath city of Uttarakhand. Even now the process of cracking in the buildings is going on. There is fear among people due to landslides. UK earth scientist Dave Petley has analyzed this crisis and tried to understand what is the real reason behind the cracks in the buildings in Joshimath. Petli believes that the cracks in buildings and other structures are not caused by land subsidence, but accelerated landslides.
‘It may be wrong to say land subsidence’
A prominent Indian geophysicist also agrees with this view. Kalachand Sen, director of the Wadia Institute of Himalayan Geology, told Hindustan Times "Landslides occur in sloping areas. This includes both vertical and horizontal movement." Please tell that Kalachand had also said on January 14 that it may be wrong to call the Joshimath crisis a case of landslide. According to Sen there are several factors that may have contributed to such a slide.
Landslides happen due to these reasons
He said, "At the moment, we are doing geophysical studies to see how subsurface factors contributed to the cracks on the surface." Sen said snowfall and inclement weather in the region was affecting data collection. They said, "Landslides can occur in a sloping area due to three to four reasons. First reason is rain, second is tectonic movement and third reason is human activities… all three are likely."
‘Some areas are severely affected’
He said that different intensity of slippery is being seen in Joshimath city. Sen said, "Some areas are less affected, while some are severely affected. As soon as we have the data, we will be able to tell how big an area can be shifted." At the same time, according to geologists SP Sati and Naveen Juyal, signs of both subsidence and sliding of Joshimath have been found.
Questions raised on Helang Bypass
Ganga Awahan member Mallika Bhanot raised questions on the construction of Helang Bypass. They said, "Toe erosion is very clearly linked to the construction of the Helang bypass under the Char Dham project. How could the government develop it into a high tourism area with mega projects if it was already known that the area was so vulnerable to landslides?"
‘Joshimath city built on debris of landslides’
M Rajeevan, Secretary Earth Sciences said, "Joshimath was developed on the debris of a landslide that occurred several hundred years ago. I am not a geologist, but from earth scientists I understand that this region is slowly collapsing due to many reasons. Slipping and dislodging is now uneven, but a large area is likely to be affected… Government should start continuous monitoring to prevent future incidents."
