    Yeah, I imagine even a 1ft tidal wave would be enough to sweep a person or a small car away.

    Apparently, there are a whole mess of magnitude scales. The 8.8 and 9.0 are given in “Mw” scale,which estimates total energy. It doesn’t differentiate between friction and the seismic wave energies.
