Search for the local centres of the Tunguska explosions

The structure of forest destruction caused by the Tunguska meteorite explosion is studied by a special method. This method consist in constructing a set of points of intersection of the directions of fallen trees and an analysis of the distribution density of this set. It is found that in addition to main epicentre of the forest destruction region, previously determined, the method indicates another critical point located about 4–6 km to the west of the main epicentre. This feature can be interpreted as a consequence of the flight and destruction of small piece of the Tunguska meteorite.
