A short film on causes and impact of disaster in Uttrakhand state in India. By Dr. Nitish Priyadarshi Geologist.    This was one of the most challenging disasters till date at Kedarnath so much so that even after few days also it was really tough for a human mind to calculate the loss.

People carrying torches and lanterns in the Ranchi  Street were common. Even the rickshaw pullers use to attach small lantern in front or back of rickshaws. Cycles were fit with dynamos.
