    On the morning of June 30, 1908 a remarkable natural phenomenon

took place in the region  to the north and north-west of Lake Baikal  in Russia,which now is usually known as Tunguska  event. Despite that dozens explanations have been put forward, an origin of the event is still disputable.

    Here we summ up all known facts of Tunguska event. We demonstrate that  Tunguska facts conform neither with a comet, nor with a stony asteroid fall. 

    Research reveals that  all Tunguska facts are known in association with tectonic and meteorological activity, just maybe on smaller scales. Also the event was associated with peculiar and rare combination of tectonic and meteorological activity on regional level, and partly on even larger scales. This points to the idea that Tunguska event was of geophysical origin.
