Dehradun, February 9: The death toll from the Uttarakhand disaster rose to 31 with the recovery of five bodies on Tuesday, the State Emergency Operation Centre said, even as the operation to rescue around 30 workers feared trapped inside a tunnel at the Tapovan power project in Chamoli district continued.

The State Emergency Operation Centre said 175 people are still missing after the Sunday's disaster, apparently caused by a glacier burst. The National Disaster Response Force (NDRF) earlier said its personnel recovered two bodies from debris in Raini village on Tuesday morning.

Uttarakhand Chief Minister Trivendra Singh Rawat visited Lata in Chamoli district on Tuesday to meet the residents of the avalanche-hit villages.

Rawat, who reached Tapovan on Monday evening to review rescue efforts, undertook an aerial survey of the affected areas on Tuesday and also met 12 workers who were rescued from the tunnel on Sunday evening. Uttarakhand Glacier Burst: 30 Dead, Around 170 People Missing, CM Trivendra Singh Rawat Conducts Aerial Survey; All You Need To Know.

Around half a dozen people were injured in the Sunday avalanche. Thirteen border villages of Joshimath block were cut off following the avalanche in Rishi Ganga river on Sunday. The villages that lost road connectivity in the wake of the calamity are Raini Palli, Pang, Lata, Suraithota, Suki, Bhalgaon, Tolma, Fagrasu, Long Segdi, Gahar, Bhangyul, Juwagwad and Jugju.

Nearly 100 ration kits have been supplied to the affected villages by helicopters to ensure they face no dearth of essentials. Talking to reporters, Rawat said the priority is to get to those trapped inside the tunnel and save as many lives as possible.

Additional heavy machines could be pressed into service to expedite the process of clearing tonnes of debris inside the tunnel blocking the path of rescue personnel.
