It's about power. I can cause a lot of damage to fluff objects over seconds or I can cause damage to a far more durable objects nearly instantly. Superman sliced through structural steel nearly instantly. He swipes the ground for a few moments and create devastating results.Superman can achieve the feat with a punch.
Superman can punch more than 1/100th the speed of light. From the flash scene we see Superman throw his first punch as lightning from Flash travels and hits the statue. Lightning is about 1/3rd the speed of light. So if Superman punched with 1/30th of the speed of that lightning stroke (it was visually closer to 1/10th) then he punched with more than 1/100th of the speed of light. The kinetic energy he could impart in the ground is more than enough(more than 2e13J or more than 1/20th of a typical hydrogen bomb).
You forget, we saw those punches land and they didn't do 1,000,000th the damage you're claiming.
