    I don't know if the depth of it was different, or since it's a logarithmic scale it was just that much weaker, but Russia reported 10-12ft tsunami waves (which is admittedly way too much) Japan reported 2ft, and California got between 2ft and 5ft.

    Probably had more to do with the direction the plates shifted rather than total energy of the shift I guess

    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.

      Hazardous waves from strong 8.7 quake are possible on the coast of Russia, Hawaii, Alaska and some Pacific islands after earthquake struck off Kamchatka

        It’s pretty normal for eruptions and earthquakes to happen together. They are symptoms of the same cause: plate movements.

          We even had an advisory in Okinawa. Gave my family and I a scare, but we were ok.

              Yes, thank you for asking. I think they recorded 10cm difference on the island but I'm not aware of any damage, injury, nor death.
