Assuming a worst-case scenario, where the asteroid impacted a populated area, the effects could include a blast wave, thermal radiation, and the release of debris and ejecta into the atmosphere.

blast wave - supersonic shock wave
thermal radiation - most of it will burn up in the atmosphere
Can we pick the city? I have a list of suggestions.
