Quizplus · Accepted Answer

Tunguska refers to an asteroid impact that occurred in Siberia in 1908, which is also known as the Tunguska event. It is estimated to have been an explosion equivalent to 5-15 megatons of TNT, and caused widespread damage to the surrounding area. The asteroid is believed to have disintegrated in the atmosphere, which is why no crater has been found at the site.
