Earth Release: Rock Avalanche Technique

While standing near a rocky surface, the user extends one hand towards the target, the index and middle fingers outstretched, and the others bent. This prompts the nearby surface to be split into boulders of various sizes, which are lifted into the air and sent flying at the target with a great amount of force and cause a huge blast.

Hiyama Machi has shown enough prowess with this technique to create the rocky surface in sand, and even water.
