Abstract :

6.12.2016 at 18:36 local time (18-36 UTC) on the territory of the Republic of Khakassia, there was a rare astronomical phenomenon that thousands of people could seeâ�?�?it was a fall of large enough astronomical body. In spite of the fact that this fall didnâ�?�?t cause damage it was necessary to say that the most powerful impact wave was near high-security objectsâ�?�?Maina and Sayano-Shushenskaya HPP. The last one was equipped with the local seismological net which the explosion impact wave was recorded on (Figure 1). The analysis of data from surveillance cameras and dashboard cameras showed that the azimuth of meteoroid trajectory was 1350�?±100, and the luminous trace finished over the seismological net surrounding Sayano-Shushenskaya HPP. The interpretation of seismologic data let us specify in a substantial way the trajectory of bolide flight and determine the territory of potential falling out of meteor body fragments. At the moment of explosion, there was a surface seismic wave, amplitude was incomparably lower than same of Chelyabinsk meteoroid explosion and it was recorded only by seismic stations situated at the distance of 10 km from the epicentrum.
