GEOLOGY

Detailed explanation-1: -Earthquakes are the result of sudden movement along faults within the Earth. The movement releases stored-up ‘elastic strain’ energy in the form of seismic waves, which propagate through the Earth and cause the ground surface to shake.

Detailed explanation-2: -The energy typically released in an earthquake is kinetic energy, thermal energy and sound energy. The kinetic energy associated with an earthquake is due to the movement of the ground. The thermal energy comes from the friction force that exists in the fault.

Detailed explanation-3: -An earthquake is a trembling or shaking of the ground that is caused by a release of energy stored in rocks beneath the surface of the earth.. There are great forces that take place beneath the surface of the earth that put a stress on these rocks, which bend or change the volume in the rocks.

Detailed explanation-4: -1) Energy for Earthquakes comes from radioactive energy in Earth’s mantle. Radioactive decay produces heat that causes convection in the mantle. This movement is transferred to Earth’s crust where movement stores up energy in rocks, like a spring being stretched.

Detailed explanation-5: -Ground shaking is a term used to describe the vibration of the ground during an earthquake. Ground shaking is caused by body waves and surface waves. As a generalization, the severity of ground shaking increases as magnitude increases and decreases as distance from the causative fault increases.
