June 30th 1908: Tunguska event On this day in 1908 just after 7.00am a very powerful explosion occurred in the skies above Siberia, in modern day Russia. The explosion was caused by the breakup and impact of a large meteorite. It was the largest impact event in Earth’s recorded history. The explosion was 1,000 times more powerful than the atomic bomb dropped on Hiroshima. Around 80 million trees were knocked down by the shock wave from the impact. The cause of the event puzzled scientists for many years, but it has recently been established that a meteorite was the cause.
