Earthquakes occurring at a depth of less than 70 km are classified as 'shallow-focus' earthquakes, while those with a focal-depth between 70 and 300 km are commonly termed 'mid-focus' or 'intermediate-depth' earthquake.

Epicenter
An earthquake occurs deep in the earths crust caused by the displacement of two faults in the crust. Directly above the fault on the earths surface is called the epicenter. Which shows the aftermath of the strike slip fault that occured in the earths crust. So the strike slip fault is the effect of the displacement of the crust at that point deep in the earths crust which causes an earthquake to happen whenever there is a displacement of two faults.
Mostly the sedimentary part which involves the process of weathering, and diagenesis occurs at the earths surface.
The point underground where the energy is released (causing the earthquake) is the focus point. This area is the actual origin of the earthquake. It should not be confused with the epicenter, which is the point above ground where the earthquake originates.
Epicenter
it get weak
A shallow earthquake occurs at a shorter depth from the surface of land, which can result in a louder, stronger quake. As an example, in 2011-2012, Ohio had a series of shallow quakes less than 2 miles beneath the surface, related to shale drilling. An intermediate earthquake occurs at a deeper depth than a shallow quake and likely involves natural fault lines.

Focus
The surface of the earth moves violently in an earthquake. This occurs when there is a sudden release of energy in the earths crust. Anything from a volcano to a tectonic plate shift can cause an earthquake.
If the fault is responsible for the earthquake, there will be movement (displacement) along the fault.
the shaking of the earthquake
Earthquakes occur underground and are felt on the surface. The center of an earthquake on the surface is called the epicenter, and the center of the earthquake underground, where it occurs, is called the hypocenter or focus.
