The Indian Space Research Organization’s National Remote Sensing Center has released satellite images of Joshimath, a village in Uttarakhand that is slowly sinking due to land subsidence, and by 2022 A rapid subsidence of 5.4 cm was recorded in the 12 days between December 27, 2011 and 27 December. Between April 2022 and November 2022, the 12-day subsidence accelerated, with Joshimath showing a slower subsidence of 9cm. NSRC said last week that rapid subsidence events were triggered between December and the first week of January.
The subsidence zone is only located in the central Zoshimas, including the army helipad and Narsingh Mandir, satellite images have shown. The crown of subsidence is near the Joshimath-Auli road at an elevation of 2,180 m.
Joshimath was declared a subsidence zone by the Chamoli district administration after hundreds of homes developed cracks within days and their residences were identified as unsafe, forcing families to relocate. Demolition of the two hotels began on Thursday but was again halted due to bad weather while the government announced a temporary relief package of Rs 1.5 million and work on a rehabilitation package. The demolition of the machine was suspended for several days due to protests from locals and residents.
Only the Malari Inn and Mount View Hotel will be demolished as they pose a danger to surrounding structures, and the administration has now assured that no other homes will be demolished. Several teams of experts have been involved to analyze Joshimath’s sinking, and the NTPC Heidel Project’s tunneling work has been criticized by experts. However, the NTPC issued a statement and claimed that the tunnel did not pass under Joshimath.
