Re: Fireball Detection . . .
What none of the articles or press releases do is to make a meaningful comparison between the different events.
However, I spent a few minutes comparing releases and it appears that the total radiated energy (a crude measure of the size of the meteoroid) was no larger in this Siberian event than in many other events over the last few years.
It is therefore highly unlikely that anything large hit the ground, and quite improbable that this is anything remotely like Tunguska.
