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.
