To Kento's second post: Not really. We don't see them often crush the environment, but check out some of the movies, say, of Yu Yu Hakusho. That has an entire plane of existence and a good portion of Japan devastated. The Toguro fight empties a stadium of demons. Sensui blows up huge portions of the Earth. Even in Naruto, just check out what the fights between Zabuza and Kakashi or a pretty basic Rasengan or Chidori or the tripolar fight of Tsunade, Orochimaru and Jiraiya when they summoned their animals. Look at the devastation that Zorro's fight with Mr. My Body's Metal wreaked and the type of hits Zorro could take. And these examples are from EARLY in these series.
My fighting philosophy is: It's not all about measuring what cross-section of the Earth someone could sever in one blow. It's about technique, strategy, a wide variety of physical and mental attributes, etc. Someone could conceivably not be able to do as much raw damage with a punch and yet have so much better control, targeting skill, ability, etc. that they'd cream the other guy. Muhammed Ali didn't hit as hard as most of his competition, but he punched 1/20 a second. Bruce Lee wasn't just fast because of muscles, but because of his incredible positioning, quickness of mind and body, coordination, emotional sureness and mushin/zanshin style skills.
