Nellore:Satellite images showed the extent of damage caused by a cloudburst at Dharali, Uttarkashi district, Uttarakhand, on August 5, where 128 people were rescued by Friday noon. So far, 566 people have been rescued since Tuesday, when torrents of mud swallowed homes, hotels and cars.
Sixteen people, including nine Army personnel and seven civilians, were listed missing but residents of nearby villages, like Mukhba said the number was likely higher as locals and labourers from Bihar and Nepal were working at under-construction hotels and were staying in the disaster-hit township.
Dharali is the main stopover on the way to Gangotri, from where the Ganga originates, abounding in hotels, homestays, restaurants and guest houses.
The National Remote Sensing Centre (NRSC) of the Indian Space Research Organisation conducted a rapid damage assessment using high-resolution satellite imagery from India’s Cartosat-2S satellites. A comparative analysis of the pictures taken on June 13, 2024, and those captured on August 7, two days after the disaster, revealed the full scale and intensity of the damage.
Key findings from the satellite analysis include, clear evidence of flash flooding, with significantly widened stream channels, altered river courses, and extensive damage to both infrastructure and human life.
A large, fan-shaped sediment and debris deposit covering approximately 20 hectares (750m x 450m) was found at Dharali, located at the confluence of the Kheer Gad and Bhagirathi rivers.
Several buildings within the flood zone have either been destroyed or are no longer visible. Numerous structures in Dharali appear to be buried under thick layers of mud and debris.
