This statement is incorrect. The point directly above the focus of an earthquake is called the epicenter, not the S wave. S waves are one type of seismic wave that travel through the Earth's interior during an earthquake.
The Secondary or S-wave.

No, the point directly above the focus of an earthquake is called the epicenter. The S wave is one of the types of seismic waves that are generated during an earthquake and move slower than the P wave.

S waves, or Secondary waves, are earthquake waves during an earthquake. They crash after P waves ( Primary waves) and are less stronger than surface waves
