Shallow focus earthquakes occur at depths of 70 km with magnitudes ranging from 1-5. Deep focus earthquakes occur at depths from 300-700 km and magnitudes from 6-10.
Shallow focus earthquakes generally cause more damage.
Within or adjacent to faults.
At divergent and transform boundaries.
shallow focus Intermediate focus Deep focus
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.

The difference between the epicentre and the focus of earthquakes is this:The focus of the earthquake is where the actual earthquake occurred and the epicentre is on the ground directly above the focus. The epicentre is used to say where the earthquake was in relation to places near where it occurred.Hope this helped :)
