that shockwave sure got there quick.

wow, thats imprssive. Whats up with the vertical 'rainbow' shockwave that preceeds the ground level one? I've never seen anything like that.

I'd venture the guess that this rainbow-shockwave is the result of highly compressed air from a first blast to the left, immediately followed by the blast to the right, this compresses the air and the third blast in the middle of the two previous blasts presses the air up and sideways, which results in the perceived peculiar shape of the blastwave.

Ya that is an awesome blast, right after the shockwave hits you can here the shrapnel and rocks ricocheting around.
I dont know what causes that "rainbow" effect either but if you pause it at just the right moment, you can clearly see 3 of them side by side.
