I'm saying that West coast America got hit by the initial Bow Wave from the Space fold jump. There is a reason Why the Zentradi were shocked by the fortress performing a fold maneuver so close to the planets surface. It wasn't just possible damage to the ship, nor the sizable piece of real estate they took with them.
The Fold took all displaced mass that and drew a line in the direction of the fold. This created an amplified wave greater than the suddenly missing island could account for, and it had a direction it was moving in.
