When I was a kid we'd drop H100's in a lake and every once in awhile stun some fish if the fuse was long enough for them to sink. Drop a boulder in and you don't stun squat.
It doens't take but a sustained "wave" of a couple of millimeters to cause this type of destruction. I'm taking about a couple of mm in the deep ocean and the width of the wave(front to back) is several miles, not a couple of feet like normal waves. Do a little reasearch first before you sound like a know-it-all who doesn't know anything.
It's not a shockwave. It's just a wave, albeit a big one. Shock waves are supersonic.

Why are you comparing explosives to boulders? Do an energy, and power calculation. Dropping a boulder in has very little energy, not much power, since the energy is released slowly, relative to fireworks. Also, quantity has a quality all its own. Try dropping several million tons of rocks in and see what happens.
But primarily, we aren't talking here about "stunning," we're talking about a water displacement that turns into a massive wave on the other side of the ocean when it hits shallower water. Your boyhood experiences are entirely irrelevant. It's the physics and calculations that count, not irrelevant anecdotes.
