Abstract: In the early morning of 30 June 1908, hell broke loose near the Stony Tunguska river in Siberia, and the majority of trees were felled in an area of more than , in an approximately radial pattern. The suspected cause has been an impacting meteorite, either stony or icy, and has entered published diagrams as a milestone of impact statistics. But no trace of an impacted body has ever been found. All the morphological and chemical evidence conforms with outgassings or earthquakes. The `telegraph poles' near the epicenter remind of the Hiroshima nuclear bomb, and the four `bright nights' are reminiscent of the 1883 Krakatao eruption. In fact, more than a dozen reasons will be presented that Tunguska was a recent kimberlite, i.e. a volcanic event.
