S-waves

Then the earth shook and trembled; The foundations of the hills also quaked and were shaken, Because He was angry.

(Psalms 18:7) NKJV

In seismology, S-waves, secondary waves, or shear waves (sometimes called an elastic S-wave) are a type of elastic wave, and are one of the two main types of elastic body waves, so named because they move through the body of an object, unlike surface waves.

– S-wave, definition (Wikipedia)

S-waves, secondary or shear waves, travel through the Earth’s crust and mantle, they can only propagate through solid material. Shear forces don’t exist in liquids or gas.

Here’s a quote from Journeys to the Center of the Earth by Tim Folger for Discover Magazine, about the development of the current theory of the internal structure of the Earth.

An earthquake powerful enough to be felt occurs somewhere in the world about once every 30 minutes. Each releases a variety of seismic waves. In addition to the waves that distort Earth’s surface and cause so much destruction, earthquakes spawn two other types of seismic energy that ricochet through the body of the entire planet. Primary waves, or P-waves, compress the layers of rock or liquid they pass through. They move at more than 16,000 feet per second through granite. Secondary waves, or S-waves, pull rocks apart as they undulate through the planet, creating what scientists call shear forces. Traveling at about half the speed of P-waves, they’re the second type of wave to reach seismographs, hence their name.

Secondary waves move only through solids; shear forces don’t exist in liquids (since liquids can’t be torn apart). The speeds and paths of both types of waves vary with the density and elasticity of the materials they encounter. Whenever the waves reach a boundary between regions differing in density or other properties, they are deflected from their trajectories. By analyzing these sorts of data from seismic waves, scientists can identify the rocks and metals that make up Earth’s mantle and core.

P-waves travel through gas giving no reason why what popular science (SciPop) calls the “liquid outer core” can’t be open space. Jesus describes it in the parable of the rich man and Lazarus.
