a several kiloton blast could not go through the crust far enough to cause the super volcano to erupt. Even a 100 MEGATON blast would have a low chance of setting the volcano to erupt at full power(well, low being in the 20-50% chance, but still, that a lot more than any orbital strike can provide that's currently in orbit around earth).
