Ground Zero allows you to pick a place and a bomb and nuke an area.

Unfortunately it hops from 21 kT to 400 kT, but still.

This is actually completely useless since these explosions are far closer to the earth -- probably between 100 meters and 1 km altitude [1], vs. 10-30 km estimates for this meteor. Also, it only shows thermal radiation effects, which are insignificant here.

This is an appropriate calculator for meteors [2-3], including the effects of the actual blast (overpressure), not just heat. The documentation says windows are shattered at about 6,900 Pa (1 psi).
