Footage has emerged of a huge explosion caused by the Russian Army in an effort to blow up a massive boulder that was blocking a river.

The video shows the military taking care of a 140-meter-long, 11-meter-deep rock jam that blocked the Bureya River in Russia’s Far East after a landslide – in a way they do the best.

With the energy of some 20 tons of TNT, the fiery explosion hits the ice-bound river, sending gigantic plumes of smoke into the air and making the ground shake.

In all, the operation to tackle the jam required more than 530 people and 6 army helicopters, the military said.

They also deployed the new Russian drone, the Orlan-10, to aid in the task of freeing the river, which has the largest regional hydropower plant with gravity dam built on it.
