They're seismic waves. seismic waves are waves of energy that travel through the Earth's layers, and are a result of an earthquake, explosion, or a volcano that imparts low-frequency acoustic energy. Many other natural and anthropogenic sources create low amplitude waves commonly referred to as ambient vibrations. Seismic waves are studied by geophysicists called seismologists. Seismic wave fields are recorded by a seismometer, hydrophone (in water), or accelerometer.
Body waves are seismic waves that travel through the earth, rather than across the surface. body waves generally have higher speeds and shorter wave lengths than surface waves. .
P waves and S waves
Primary Waves, Secondary Waves, and Surface Waves.
fluids usually transmit only what type of waves
The two main categories of seismic waves are body waves and surface waves. Body waves can travel through the earth's inner layers, but surface waves can only move along the surface of the Earth.
The P Waves. Then the S Waves.
P and S waves are body waves.
Body Waves
S waves
A Body Wave.
P waves and S waves
The body tissue that transmits waves of excitation is nervous tissue. This type of tissue is found in the nervous system and it is made up of neurons.
Seismic waves are generated by earthquakes. These can be further divided into surface (Rayleigh and Love) waves and body waves (P and S wave).
A body wave is a seismic wave that moves through the interior of the earth, as opposed to surface waves that travel near the earth's surface. P and S waves are body waves. Each type of wave shakes the ground in different ways.

Those are "millimeter waves" ... radio waves in the general neighborhood of 300 GHz.
