New Delhi: The Indian Space Research Organisation (ISRO) on Friday released satellite images of Joshimath and a preliminary report on land subsidence which shows that the entire town may sink. The pictures are taken from the Cartosat-2S satellite. According to the report, the land subsidence was slow between April and November 2022, during which Joshimath had sunk by 8.9 cm. But between December 27, 2022, and January 8, 2023, the intensity of land subsidence increased and the town sank by 5.4 cm in these 12 days.
