Take a look at this:
http://www.narutoforums.com/blog.php?b=14692 If we calc the fragmentation energy required to destroy that volume of rock, we get: 14.2 megatons. Not much unfortunately. But, remember this: Yomi stated that he, even using 1/3rd of his power, is stronger than Hokushin, Rinku, Chu, Touya, Jin, Shishi, Suzaki, Kurama and Yusuke. This not some power level shit but direct statement combined with good old 'I am x times stronger than you' linear scaling. Each of those 9 guys are stronger than CB saga Yusuke. So, Yomi’s energy output, at the minimum, should be 14.2*9*3 = 383.4 megatons. Convert it to joule and we get 1.6e+18 joules of energy output. Thats bonafide island level. In comparison, the Tsar Bomba capped at 50 megatons. So Yomi has more than 7x the output of the strongest bomb ever. Island level destructive capacity for Yomi sounds good.
