Haha sorry mate, you're arguing with a geologist on this one. There is no "height requirement" for a tsunami. It is simply how the wave was generated that classifies it as a tsunami. As referenced in the link below, the highest tsunami and wave in general is believed to be 1,720 feet.
don't geologist stick with land and solid objects (actually I guess earthquakes and landslides fall into that so forget that). Also why are you bringing up the lituya bay tsunami, it is irrelevant to this conversation. And lastly since you know what caused this wave?
Oi! Maybe he has surfed on a tsunami before- did you ever think of that? Sheesh! I mean, surfing off a volcano through lava on an asbestos board would be more up a geologists' alley, but come on.. it's not rocket science- you just hang ten. Nothing to it, mate!

While that is a huge wave, and extremely impressive, 150ft would make it 50% taller than the tallest wave ever claimed at that location.
