An S wave is slower than a P wave and only moves through solid rock. This wave moves rock up and down, or side-to-side. Because P waves are compression waves, they can move through a liquid. However, S waves cannot move through a liquid. This is because a liquid is not rigid enough to transmit an S wave.
All of the water above it also rises or falls, forming a high point (called a wave crest) or low point (a wave trough) in the water. In this way, each shudder or jolt of the earthquake sends out another tsunami front. In the very deep water of the open ocean, tsunamis travel quickly and spread out from one another. The spacing within a series of seismic waves can be as much as 100 miles (160 kilometers). A newborn tsunami traveling in open water is virtually invisible.
