The Indian town of Joshimath, known as a gateway to the Himalayas, sank by 5.4cm, sometime between late December and early January, the Indian space agency has reported. The popular tourist destination, at an altitude of over 6,000 ft (1800 meters), is prone to subsidence, partially due to infrastructure development.
A report by the Indian Space Research Organisation (ISRO) was released on Wednesday and detailed changes detected by satellite observation in Joshimath. A rapid subsidence event was triggered sometime between December 27, 2022 and January 8, 2023, the National Remote Sensing Centre said. According to witness accounts, it most likely happened around January 2, it added.

Thousands of people have been killed over the decades of its existence from natural disasters, including earthquakes, landslides, flash floods, and avalanches. The Uttarakhand floods in February 2021 alone claimed over 80 lives, with more than 120 people missing.

Subsidence has affected Joshimath for some time, with the impact magnified by the depletion of groundwater for irrigation and the rapid development of infrastructure, including the construction of hydropower plants, according to scientists.

Soil movements damage roads and walls, often making people’s homes unsafe to live in. Uttarakhand Chief Minister Pushkar Singh Dhami ordered a mass evacuation last week, after a survey conducted by the district administration found deep cracks in 603 buildings in the town.
