The energy of the quake is transmitted through the ground. It's that simple. There are a couple of different waves that move through the earth, and you know them as the longitudinal and transverse waves, the so-called seismic P-waves and S-waves, respectively. A parting idea might be that an earthquake is the release of (seismic) mechanical energy, and, as with all mechanical enery, that energy is transferred into and is carried by the wave. You'll find a link below.

The velocity of seismic waves is dependent on the density and stiffness of the the material (more specifically the bulk and shear modulus). P wave velocities are typically in the range of 6-8 km/s and S-wave velocity is typically around 60% of that of the P-wave.

How do earthquakes release the energy of frictional stress?

Earthquakes release the energy of frictional stress stored in the Earth's crust by causing the rocks along a fault line to suddenly slip past each other. This sudden movement generates seismic waves that propagate through the Earth, creating the shaking and ground motion associated with earthquakes.


Which events are NOT given by solar energy?

Events that are not directly given by solar energy include volcanic eruptions, earthquakes, and thunderstorms, as they are driven by other geological or atmospheric processes.


Why is fires the leading cause for earthquakes?

fires are not the leading cause of earthquakes. The earth is covered in massive plates that move around. When these plates rub against each other massive amounts of energy is built up. Earthquakes are the release of this energy.


What causes more damage shallow or deep focus earthquakes?

Shallow-focus earthquakes cause more damage than deep-focus earthquakes. This is because shallow-focus earthquakes originate closer to the Earth's surface, which allows the energy to be more concentrated and lead to stronger shaking and more destruction of structures. Deep-focus earthquakes, occurring deeper underground, tend to have their energy dissipate before reaching the surface.


Why not all movement along faults produce earthquakes?

Faults DO NOT produce earthquakes, faults are produced by earthquakes. This means that earthquake loci are centered on and along faults. The energy released by an earthquake is the strain energy built up as a result of plate tectonic forces. Some faults move easily and thus no strain energy builds up.
