I haven't seen a helpful answer to the original question.  Any land motion
took place under water.  It didn't fall from a cliff or fall into a
trench.  The boundary between plates moved.  And I don't see why there is
wave motion.  If the land sank, where did it go? Maybe a geo type can
explain this.

And I wish the media would not call it a tidal wave.
