n MNASSA : Monthly Notes of the Astronomical Society of South Africa - Tunguska at 100 : news note




On the 30th of June 1908, exactly 100 years ago this month, a large airblast occurred in the Siberian taiga, near the Podkamennaya Tunguska River. It has become widely known as the "Tunguska Event". Environmental effects of the explosion were observed in almost the whole northern hemisphere and many traces of the impact are still well preserved in the epicentre area. In spite of all the efforts of several generations of scientists from different disciplines and from many countries, there are still some unanswered questions.
