Meteor fall in Russia

Did you hear about the Meteor fall in Russia?
Apparently a meteor of the size of  a Bus entered the atmosphere of the earth at a speed of nearly 33000-40000 miles/hr (~ 54000kms/hr). It exploded about 30-50 kms above the surface of the earth which was fortunate for the residents of the city of Chelyabinsk with a population of ~ 1 million people.
The force of this explosion was as large as 20 times that of Hiroshima bomb.
In spite of the fact that it exploded nearly 30-50 kms above the surface of the earth, 1100 people were injured because of the after shock wave generated out of the explosion. In the same explosion would  have taken place a little later more nearer to the surface, the devastation would have been severe  as that Hiroshima or Nagasaki bomb explosion.
The force of this explosion was as large as 20 times that of Hiroshima explosion.
Apparently there was an asteroid which was supposed to pass Earth around at the same time, but these two planetary motions have no connections.
Seems people had relaxed a bit considering that 2012 is over without any natural calamity other than Japan's earth quake. But this incidence had once again brought in attention the destructive nature of the nature's forces.
