➡ Generally, volcanic eruptions are the main causes for formation or occurrence of Earthquakes. During the volcanic eruptions, hit gases are pushed upward and they pushed violently the Earth's crust surface upward, resulting in Earthquakes.

➡ The tectonic earthquakes are most frequent. They occur when the inter-plates collide with each other along their surface-contact edges.

➡ Internal horizontal and vertical movements due to come ressional and tensional forces cause folding and faulting in the Earth's crust resulting in the ocurrence of Earthquakes.

➡ Some man made causes include construction of huge dams, nuclear explosions, blasting of rocks, mining, etc.

Answer 2

Earthquakes are usually caused when rock underground suddenly breaks along a fault. This sudden release of energy causes the seismic waves that make the ground shake. When two blocks of rock or two plates are rubbing against each other, they stick a little.
