Tunguska Impact: How Far Can We Move Up in Our Prediction of the Past?
The Tunguska impact happened in 1908 in Siberia, causing the vast destruction of the forest in the area of about 108 m2; it was accompanied by an explosion–like phenomena . The 1908 catastrophe caused the destruction of 80 million trees, seismic waves, magnetic storms and bright nights across Eurasia. The observation data is limited to the fallen trees, registered seismic waves and controversial description of some locals. In spite of vast efforts of many expeditions to the area of the impact, neither solid debris of the Tunguska object nor craters have been found. Thus, there are many uncertainties in the interpretation of that “mysterious” event. For 100 years, there have been numerous discussions on the parameters of the Tunguska body. Even its nature is still unclear and attracts very different points of view (see , , , ). There have also been many publications related to the investigation of this problem including numerical simulation of different scenarios of the impact, see, e.g., , , , , , , . Most research in this field is based on 2D (axisymmetric) modeling while paper  provides 3D analysis.
