Experts from a range of central institutions- NDMA, NIDM, Geological Survey of India, IIT Roorkee, Wadia Institute of Himalayan Geology, National Institute of Hydrology and Central Building Research Institute should work closely with Uttarakhand in the spirit of "Whole of Government" approach.

A clear time-bound reconstruction plan must be prepared and continuous seismic monitoring must be done, he said, adding that a risk-sensitive urban development plan for Joshimath should also be developed.

The review meeting was attended by the cabinet secretary, other senior officials of the central government and members of the NDMA besides the chief secretary and the DGP of the state through video-conference. District officials of Joshimath also attended the meeting.

Experts from IIT Roorkee, the Geological Survey of India and the Wadia Institute of Himalayan Geology also participated. Dhami had visited Joshimath on Saturday to assess the situation on the ground, a day after he directed the immediate evacuation of around 600 affected families.

Giving details of the relief and rescue efforts, Chamoli District Magistrate Himanshu Khurana said 229 rooms with capacity to accommodate 1,271 people have been identified at different locations within the town. Ration kits were distributed to affected families besides an ex gratia of Rs 2.30 lakh among 46 of them at the rate of Rs 5,000 per family for buying essential household items.

DM Khurana went door-to-door requesting people living in damaged houses to vacate them and move to temporary relief centres. Uttarakhand Chief Secretary Sukhbir Singh Sandhu during his visit to the town made a similar appeal to people: "You should take no risks. The safety of residents is an immediate priority and the district administration is working continuously to ensure that".

Geological experts are exploring the causes of land subsidence. Based on their recommendations whatever treatment is needed will be done in Joshimath, the CS said. Considering the extent of damage at least 82 more families will have to be evacuated to temporary relief centres as soon as possible, Garhwal Commissioner Sushil Kumar told PTI.

Kumar heads a committee tasked with monitoring the situation on the ground level and has been camping in Joshimath since Thursday. There are a total of 4,500 buildings in Joshimath out of which 610 have developed huge cracks and are unfit for habitation, he said, adding that a survey is still underway and the number of affected buildings might go up.

"Land subsidence has been going on slowly in Joshimath for quite sometime but it has increased over the past one week with huge cracks appearing in houses, fields and roads," the Garhwal Commissioner said. "The situation worsened apparently after a water channel beneath the town erupted last week," he said.

Chief Minister Dhami who visited the affected areas in Joshimath on Saturday held a meeting with officials in Dehradun on his return and asked them to relax the norms to expedite relief operations. They were asked not to get entangled in long procedural complexities and take direct clearance from him for works related to treatment of drainage and sewage systems in Joshimath, he said.

The National Remote Sensing Centre, Hyderabad and the Indian Institute of Remote Sensing, Dehradun have been asked to conduct a study of the Joshimath area through satellite imagery and submit a detailed report with photographs.

A petition has been filed in the Delhi High Court seeking a direction to the Centre to constitute a committee headed by a retired judge to look into the issue of sinking of Joshimath and rehabilitate the affected families. Earlier, a seer had moved the Supreme Court seeking that the Joshimath crisis be declared a national disaster.

Experts have claimed that the land subsidence in Joshimath is primarily due to the National Thermal Power Corporation's Tapovan Vishnugad Hydro Power Project and is a very grave reminder that people are messing up with the environment to an extent that is irreversible.
