A meteorite explodes in the tundra

The Siberian tundra is also known for a spectacular astronomic event. On June 30th, 1908, in a remote region of central Siberia, near the river Tunguska, a meteorite having a diameter of 50 metres exploded in the earth’s atmosphere 8 km above ground. The explosion could be seen from 500 km away and the roar was heard from 1,200 km away.
Its effects were devastating: in few seconds ,every form of superior life was swept away.
Today, no signs are left of the catastrophe. Luckily, there were no settlements in the area.
