Rescue workers recovered the body of another worker from an inundated tunnel in Chamoli, Uttarakhand, on Saturday, the eighth death after a suspected aquifer burst pushed a rush of water and debris through the under-construction passage earlier this week.

Rain-saturated aquifer suspected to have triggered tunnel flood
Preliminary assessments pointed to a rain-saturated aquifer that ruptured through the roof of the 3km tunnel about 1.44km from the entrance.
Rainwater from surrounding slopes had percolated into a water-bearing layer above the tunnel and released under pressure through a weak section of rock. The force was sufficient to push a column of air ahead of the water, throwing some workers towards the tunnel mouth even as others were pinned by debris deeper inside.
