Again, this is all based on the fact that Sasuke called Deidara's hand seal the Earth Release seal, meaning that Earth Release is somehow used in the explosion, because Deidara formed the seal when his C4 exploded.

There's no indication that the Earth seal has a) to do with the creation of the clay, because the clay is already there or b) with the clay's movement, because while chakra is indeed used to move the bombs, the hand seal wasn't used when the C4 moved and c) the Earth seal isn't the seal shown when Sasuke talks about it (even though I admit that it would make more sense if the Earth seal was the Katsu seal). I'm not sure. Maybe one of the previous databooks hinted towards Earth Release? I would guess a databook. I might watch the early episodes of Shippuden again and see if they say anything about it (strangely, dubbed anime can end up stating other things due to the nature of dubbing the series).

The only thing we know is that Lightning stopped the bombs. Kakashi also stated earlier before hand, against Kakuzu, that he was using Earth Release with the Snake handsign. The Katsu handsign refers to the explosion, which doesn't imply that he was using Earth: for all we know, he could be changing the chakra flow from Earth to Explosion by using that handsign.
