Joshimath: Slow subsidence up to 9 cm is recorded in Joshimath town over a period of seven months, between April and November 2022, according to the Indian Space Research Organisation (ISRO) satellite-based report.
National Remote Sensing Centre, ISRO said several reports over the last few days highlighted the subsidence occurring in Joshimath. Due to landslide-related creep, cracks have appeared in around 700 houses. Roads along with the hotels and hospitals present there have developed cracks, said NRSC.
ISRO, in its observation, said, "Slow subsidence up to 9 cm within the Joshimath town is recorded over a period of 7 months, between April and November 2022. Between December 27, 2022 and January 8, 2023 a rapid subsidence event was triggered."
The region subsided around 5 cm within a span of a few days and the areal extent of subsidence has also increased. But it is confined to the central part of Joshimath town, said the space agency of India.
A subsidence zone resembling a generic landslide shape was identified (tapered top and fanning out at base). The Crown of the subsidence is located near Joshimath-Auli road at a height of 2,180 metre, said ISRO report.
"I have met with everyone and assured people that state administration is with the people of Joshimath. We will help everyone," CM Pushkar Dhami told the media. (with ANI inputs)
