Apophis is a tiny fraction the size of Chicxulub. True, it could still trigger massive tsunamis or earthquakes, but hardly the apocalyptic impact of Chicxulub. Anyway, as you point out, Apophis is almost certainly going to miss Earth.

The Earth's crust is moving all the time - it's called continental drift. It's a continuous cycle of continents coming together or splitting apart. It's not some single earthquake that causes this. The last supercontinent was Pangaea, and we are heading for another one in a hundred million years' time, which some call Amasia.
