The Tunguska Event - largest recorded impact event
On the 30th of June 1908 an explosion happened in the Eastern Siberia region of Russia.
It impacted an area of 2,150km2 of forest, flatenning the trees with some reports of 3 casualties; although the area is sparsely populated. The explosion is thought to have been due to a meteroid measuring about 100 metres bursting about 5 to 10 km above the ground rather than exploding on impact; this is also one of the reasons that there is no impact crater that has been found. Locals noted a column of bluish light moving across the sky with a flash and bang about 10 minutes later.
Some estimates say the burst would have measured 5.0 on the Richter scale with energy ranging from 3 to 30 megatons of TNT. The blast was enough to break windows hundreds of kilometres away as well as detection of the explosion as far away as the UK.
The Siberian Life newspaper said
When the meteorite fell, strong tremors in the ground were observed, and near the Lovat village of the Kansk uezd two strong explosions were heard, as if from large-calibre artillery.
