Earthquakes produce seismic waves that travel through the Earth.

Earthquakes
When earthquakes occur, scientists measure them using seismographs. Earthquakes produce a number of different types of waves. Some run along the surface of the earth. Some travel through the earth. Those that travel through the earth travel at different speeds. It is possible to create similar waves in a lab and measure how those waves travel through different types of materials. Since earthquakes occur all over the world, it is possible to measure the waves from all angles. Thus, if a wave travels a small distance through the core, scientists can tell by differences in speed what it would be if it traveled through all mantle material. So with the difference in speeds in different types of waves, scientists can figure out what is in the earth's interior.
They measure how waves from earthquakes travel through the earth, and they test how waves travel through liquid and solid and goo, and they compare the results to find the consistency of the inner core and other layers of the earth.
A sudden slip on a fault causes earthquakes. When the sides of a fault are pressed together due to stresses on the earth's outer layer, it slips and releases energy in waves that travel along the earth's crust, which causes the shaking during an earthquake.

The seismic waves that the earthquakes make travel slowly and scientists can track them
Earthquakes
Earthquakes almost always occur at transform boundaries.
yes
No it does not. Not in the same way the earth has earthquakes though there are adjustments due to the effect of gravity of the earth

The natural phenomenon that seismology studies earthquakes. Seismology also studies seismic waves that move though the Earth. Seismic waves result from earthquakes.
Primary waves and secondary waves (body waves). Love waves and rayleigh waves (surface waves) do not travel through the earth's mantle. Though secondary waves do not go through liquids, the asthenosphere is only a semi-liquid, so secondary waves can still go through it.
