Earthquakes can only occur within the lithosphere because rocks in the lithosphere are strong enough to store stress.

The Lithosphere according to the oxford dictionary is the rocky outer part of the Earth. The lithosphere is always moving, but very slowly. When an Earthquake occurs the Lithosphere becomes shaky and the Earthquake create ground rupture, landslides, avalanches, fires, forests destroyed and severe building damage.
