Yep, it'd blow a crater about 15-20kms across and flatten everything within a 100-400km radius, depending on the terrain. The destruction would be spread out over the greater portion of the US and into parts of Canada and Mexico. Mostly fires and such caused by hot debris raining back down from the upper atmosphere and Earth orbit.
