“The rock types in the Himalayas are very weak,” Yaspal Sundriyal, a geology professor from the H.B. Garhwal University in Uttarakhand advised CNN.

“The vertical drilling will disturb the rock formation and will cause vibrations to the mountain,” mentioned Sundriyal, who is taken into account an skilled in native rock formations.

“The rocks in the Himalayas should be treated very cautiously and with very strong support. I’m afraid drilling will disturb the soil of the rock above the tunnel.”

On website, authorities say each rescue choices – the guide horizontal dig and the vertical drilling – are thought of secure choices, however are unable to inform which is able to deem only.

“Both vertical and horizontal drilling are safe,” mentioned Harpal Singh, the previous director of India’s Border Roads Organization that maintains the nation’s street networks.

A panel of specialists advised India’s Supreme Court that building of the highways will “lead to further landslides and soil erosion in an already sensitive environment,” in line with a 2020 report by the court docket.

Authorities are investigating the reason for the tunnel collapse and are prone to study the position of drilling on the mountain. CNN has contacted the Ministry of Environment, Forest and Climate Change of India.

The tunnel’s collapse is one in all a number of latest building disasters to make headlines in India, a rustic that has been quickly reworking its infrastructure and spending billions to upgrade its transport network.

In August, more than a dozen workers were killed after a bridge underneath building collapsed within the northeastern state of Mizoram. In June, a four-lane concrete bridge that was being constructed throughout the River Ganges within the japanese state of Bihar collapsed for the second time in simply over a 12 months, elevating questions concerning the high quality of its building.

Last October, a not too long ago repaired suspension bridge gave manner within the city of Morbi in Gujarat, killing 135 individuals.
