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.

Note: I believe the above map was originally published in Evgeny Krinov's book "Giant Meteorite" 1966 Pergamon Press and might be a version of Voznesensky's map created specifically for the book rather than a facimile copy. Copyright status unknown.

The Zigel map. Version is from "Official UFO" magazine, 1976 Countrywide Publications Inc.

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 density 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. The meteor that struck at Meteor Crater was an iron meteor about 50' in diameter, and probably weighed at least 14,000 tons, or twice that of the ordinary chondrite meteor that exploded near Chelyabinsk, Russia on February 15th 2013. The Tunguska object--assuming it was a meteor with a diameter of 150' and had a density similar to the Chelyabinsk meteor--at 27 times the volume, would have weighed upwards of 180,000 tons.

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.
