That is some meteorite! Even bigger than Albania. Seriously, though, a lot more would be happening in such a collision than what shows in the artist's rendering. The meteorite would already be coming apart due to earth's gravity, and there would probably be some major electrical effects. The waves and ripples around the impact site wouldn't be forming immediately; the impact would be in slow motion on that scale, but not so slow that land waves would move relatively that fast.
