You are confusing the impulse (photonic) flow of EM energy, with the
electron carriers which move hardly at all at HF. Hint: Electrons
cannot move at the speed of light yet we know that EM energy moves at
the speed of light.

Air particles move at speed of sound. For this reason the speed of sound is
temperature dependent.
The same must be with electrons. Do not confuse the mean velocity with the
max. In air the mean speed is also close to zero.

In a somewhat similar manner, the impulse energy in a tsunami wave
travels a lot faster than the water molecule carriers which move
mostly up and down.

Water molecules move mostly horizontally. See:
http://en.wikipedia.org/wiki/Stokes_drift

Tsunami waves are hardly noticeable in the open
ocean.

Because tsunami is the simple flow.
