An earthquake is the sudden, sometimes violent movement of the earth's surface from the release of energy in the earth's crust.
The crust of the earth when it is subject to tectonic forces, bends slightly. But, because the crust is rigid, when the stress or pressure exceeds the strength of the rocks, the crust breaks and snaps into a new position. Vibrations called seismic waves are generated and travel both through the earth and along its surface. These seismic waves cause the movement we call earthquakes.
Within areas of the crust are fractures, known as faults, along which two crustal blocks have slipped or moved against each other. One block may move up while the other moves down, or one may move horizontally in one direction and the other in the opposite direction. Geologists and seismologists (scientists who study earthquakes and the processes that create them) have found that earthquakes occur repeatedly at faults, which are zones of weakness in the earth's crust.

Here you go :-)
Up until relatively recently, scientists only had unsubstantiated guesses as to what actually caused earthquakes. Even today there is still a certain amount of mystery surrounding them, but scientists have a much clearer understanding.

It is a question for geologists: broadly the answer is that an imbalance created in the plates underneath, below the earth surface, due to cracks, upsets the rhythm and results in tremors, leaving you trembling!

An earthquake is a disturbance either brought about by a tectonic plate movement, a volcanic eruption, etc.

Volcanos in some parts of the word and tectonic plates in the earth.

It is because due to imbalance on earth. Don't cut mountain.
Mountain good for balancing the planet.
