That is a tsunami, a wave that involves the entire column of water from surface to seabed. Ordinary waves involve only the first several meters of the surface; if you go down far enough, you wouldn't even know that there are waves above.
An abyssal seamount is the term used for an underwater mountain. The term "abyssal" indicates that it is located in very deep water.
The term magnitude is used to describe the size of an earthquake.
