With a bigger crater.
The Earth is HUGE. It was struck with a mars-sized body once, early in its
history. It survived, well except that a lot of material was thrown into
orbit, and later coalesced to form the Moon. Nothing currently in the asteroid
belt is large enough to actually compromise the integrity of the *Earth*.
Some, like Ceres, might be continent busters, but continents per se are
superficial structures as far as the Earhth is concerned.
