This thread made me go back and look for the study done by catastrophe
modelling company RMS on a Tunguska event over NY. Not online anymore,
but an interesting blog post still is:

>  Slooh will cover the asteroid from its flagship observatory at the
>  Institute of Astrophysics of the Canary Islands, one of the finest
>  observatory sites in the world.

>  Slooh routinely tracks potentially hazardous objects for the general
>  public to view live

>  Slooh’s live asteroid shows have attracted millions of viewers, and
>  Slooh has become a leading voice to help ensure that public awareness
>  does not wane.

>  “The Rock’s” close approach on the 19th will not bring it on a

>  the 30-meter-sized NEAs having been detected. Even a 30-meter sized
>  asteroid can cause significant damage to a major city. While not
