In the last 40 years, the map of fallen tree azimuths used for comparison with theoretical models was the one constructed on the basis of of azimuth data measured in (See image). The new map of fallen tree directions has been obtained from: 1) revised Fast data, 2) data from the 19aerophotosurveys and 3) Anfinogenov data.

Fallen trees after the Tunguska event. The Tunguska event was a large explosion, which occurred near the Podkamennaya Tunguska River in what is now Krasnoyarsk Krai, Russia. Dated (Photo by: Universal History Archive/UIG via Getty images).

The tree fall is the principal source of information on the Tunguska Cosmic Body (TCB) explosion. The data on forest devastation give information on the energy emitted and on the height of the explosion. The directions of flattened trees make it possible to calculate the coordinates of.
