The hypocenter/epicenter of an earthquake is calculated by using the seismic data of that earthquake from at least three different locations. The hypocenter/epicenter is found at the intersection of three circles centered on three observation stations, here shown in Japan, Australia and the United States. The radius of each circle is calculated from the difference in the arrival times of P- and S-waves at the corresponding station.
The red square moves with the phase velocity, while the green circles propagate with the group velocity

In physics, a standing wave, also known as a stationary wave, is a wave that oscillates in time but whose peak amplitude profile does not move in space.

Seismic waves are waves of acoustic energy that travel through the Earth.

When the entire waveform moves in one direction, it is said to be a traveling wave; by contrast, a pair of superimposed periodic waves traveling in opposite directions makes a standing wave.

Other examples of mechanical waves are seismic waves, gravity waves, surface waves, string vibrations, and vortices.

Free oscillations of the Earth are standing waves, the result of interference between two surface waves traveling in opposite directions.
