5. I believe the first two arcs are the P and S waves. |

The final is a surface wave propagated through the ocean.
Could be wrong though as I am not a geophysicist.

7. Sound is nothing more than alterations in pressure. |
|
An earthquake creates a pressure wave that spreads out as it travels through the Earth's crust and along the Earth's surface.
Hydrophones, just like microphones, pick up the pressure differentials created from those pressure waves and translates that into sound.
