Earthed

What would happen to Earth if 2000 tons of matter converted to pure energy 800 miles from its surface?

What would happen to Earth, in detail, if a sphere of 100 yards in diameter with a mass of 2000 tons were to spontaneous turn to pure energy, as per e=mc^2, 800 miles from Earth's surface?



Would the resultant super-high-energy blast wipe out all life on the planet? Would the atmosphere be entirely ionized and blown away? Would the oceans be boiled away quickly? Or would Earth simply be vaporized? Or something less drastic or in between those options? Detail is appreciated.

1. I think it depends on the energy.
   
   
   
   If its heat, the oceans would probably be scarred into molten salt (remeber that there is salt in the ocean). THe rest of life would probably be burned.
   
   
   
   If it is movement, it would probably send a wave of energy through that would vibrate the planet so severly that it would shatter
   
   
   
   No matter what happens, we die
2. 1.63E+23 J
   
   
   
   the planet recives 84E+12 watts from the sun constantly
   
   
   
   if the energy was released in one second it is 2 billion times more powerful than the sun energy we recieve. At a range of 800 miles at least 1/3 of the energy would reach the surface of the Earth. Yup, fried.

3. The energy released would be E = mc² = 2E6*(3E9)² = 18E24 J
   
   Mass of the earth is ~ 6E24 kg, so there would be about 3 J/kg (on average) for the earth to absorb.
   
   
   
   Less than 1°C temperature increase on average. Assuming all the energy went to the earth an was not radiated into space.
