Going by Sasuke's words, it should probably be the Katsu sign, but while he says it, the Earth sign is shown, so... But he didn't really say earth sign was for explosion he said it was for the clay since his clay were made up of earth chakra they became dud due to his lightning and his theory proved to be correct. The moment he used earth style hand sign the large bomb expanded and in ch 360 you can see he uses Katsu after that for explosion to make his nano bombs, every time he uses Katsu sign for explosion except this time he used earth hand sign this suggests that clay used large amount of earth chakra which required him to weave earth hand sign then creates explosion with katsu sign, so it is the clay that is made of earth chakra.
