The Chelyabinsk event was the first asteroid disaster in (at least modern) history. The damage was from the blast wave. If the body were stronger and penetrated deeper intact, the blast wave would be more damaging. In any case Chelyabinsk demonstrated
that 20-m asteroids are dangerous and that asteroids of this size are more numerous thanwas thought several years ago. The new survey telescopes like ATLAS (Tonry 2011) and LSST (Joneset al. 2009) can provide advance warning if the impactor comes from the
night side. Day side can be covered only from space.
