The day of the Tunguska Event – level 2

30-06-1908

On June 30, 1908, one of the biggest and most mysterious explosions in history happened in Eastern Siberia. Today it’s known as the Tunguska Event.

The explosion had the power of one thousand bombs in Hiroshima. The explosion broke windows 65 kilometers away. It was so strong that seismic stations in Europe recorded an unusual earthquake.

The first person who became interested in the event was Russian scientist Leonid Kulik. 19 years after the explosion, Kulik went with his expedition to the place where the explosion happened. He found a big area with 80 million trees that were lying on the ground and without branches.

Kulik thought that the explosion was caused by a meteoroid, but he didn’t find any crater.

In the next years, many expeditions went to the area. No expedition was able to clearly explain why the explosion happened. Many people think that it was a 100-meter meteoroid that exploded about 7 kilometers above the ground.

Difficult words: mysterious (difficult to explain), event (an interesting situation), seismic station (a station which records earthquakes), cause (to be the reason for something), meteoroid (a big stone which travels through space), crater (a round hole in the ground after an explosion).
