1. Are you talking about a specific cross section which you have? Without seeing it, there is no way to answer the question.
2. Are you talking about in general? It depends on how deep the soil samples were obtained or if in a trench-type sampling, it depends on what you are seeing. For example, if your plug sample is only 6" deep then that is as deep as the cross section shows! If you dig a trench 4' deep and then look at the side and see that the soil extends down to 18", then the cross section would show 18" as the depth.
The epicenter is located on the earth's surface, right above the part beneath the earth's surface where an earthquake originates. The part of beneath the earth's surface is called the focus.

geothermal energy
Molten rock beneath the earth's surface is called magma.
The forces that drive the rock cycle beneath the earth's surface are not the same as the forces that drive the rock cycle on or near earth's surface because the processes of the rock cycle beneath the earth surface and above the earth surface are diffferent.

It is a cross section of the Earth. It has no specific name. You can find one at the link below

magma, but when its on the surface lava
It is magma
Taken along a line drawn on a map, it is a diagram of the structure and position of the rock layers present beneath the surface along this line. Geologists learn how to construct this 3rd dimensional information from a Geologic map, If you want to know how to get at an ore body hidden underground, you need a Geologist to work out where and how deep to dig. Cross sections will be needed to do this.

This is known as an earthquake.
