The centerpoint was 35deg50' N, 98deg 35' W, roughly in the center of the lower 48. Approximate radius of the effect was 2100km, which covers the contiguous US plus a fair bit more. However, the effect is not perfectly spherical, and follows the borders of the United and Confederate States more or less exactly ( some ocean for the claimed waters).
As for who, how and why.
Who: Alien Space Bats
How: Undetermined, but probably involving Q-like powers or something that can fake Q-like powers.
Why: Because they can.
