GEOLOGY

Detailed explanation-1: -Faults are cracks in the earth’s crust along which there is movement. These can be massive (the boundaries between the tectonic plates themselves) or very small. If tension builds up along a fault and then is suddenly released, the result is an earthquake.

Detailed explanation-2: -A fault is a fracture, or break, in Earth’s lithosphere, along which blocks of rock move past each other. A sudden release of stress in the lithosphere causes an earthquake. Shaking and trembling of the earth’s crust.

Detailed explanation-3: -Surface rupture occurs when movement on a fault deep within the earth breaks through to the surface.

Detailed explanation-4: -Active fault – An active fault is a fault that is likely to have another earthquake sometime in the future. Faults are commonly considered to be active if there has been movement observed or evidence of seismic activity during the last 10, 000 years.
