A stream near a beach gets dammed by the sand each year, building a reservoir of millions of gallons of water. By digging a trench in that sand, these guys create great waves of fresh water rushing into the ocean.

He slips and falls off the pier then the wave bashes him good!

This guy is nuts. Look at the size of the wave he is surfing on.

A glacier breaks apart and causes a massive wave.

"I filmed my monitors playing a 61 hertz sine wave tone at 60fps. I expected to just see the speaker slowly move in and out, but ended up with a weird wobble effect. I believe it's because of the rolling shutter effect in DSLR cameras."

Fishing during a hurricane never ends well.

That's one way to eliminate the competition.

Like a Boss...

Oh man that sux! A rogue wave swept this guy away while he was filming. Wait for it...
