The first trajectory map created from eyewitness accounts. It was put
together by A.V. Voznesensky, former head of the Irkutsk Observatory,
in the mid 1920s and used by Kulik in his search for the epicenter. It
came within 44 miles of the epicenter.

The Zigel map
A population density map of east Asia (circa 1972) with the
Zigel-Roerich trajectory overlaid. The map is, of course, 64 years too
young to represent the actual population diversity of 1908, but it
gives some idea of the population spread over the whole of east Asia
and Russia in comparison with the Zigel-Roerich trajectory.
A diagram that I drew up just for the novelty. It compares the Tunguska
forest fall (butterfly pattern) to Meteor Crater in Arizona.
A micro-barograph recording (barogram) of the Tunguska explosion. A
barograph is an instrument that records changes in air pressure, not to
be confused with a seismograph, which, of course, measures earthquake
magnitude. It was recorded the morning of June 30th, 1908 at South
Kensington, London, England. As you can see, the Tunguska explosion
appears to be separated by two distinct events. A low frequency event
followed by a high frequency event. The high frequency event would be
more characteristic of a nuclear explosion.
