Detailed explanation-1: -Earthquakes occur along faults. 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.
Detailed explanation-2: -A strike-fault has a strike parallel to that of the ore-body. A dip-fault has a strike about at right angles to the strike of the ore-body. An oblique fault has a direction between that of a strike fault and that of a dip fault. The slip is the distance between the broken ends of the ore-body, measured along the fault.
Detailed explanation-3: -An earthquake is a shaking of the ground caused by the sudden movement of large blocks of rock along a fault.
Detailed explanation-4: -When rocks break in response to stress, the resulting break is called a fracture. If rocks on one side of the break shift relative to rocks on the other side, then the fracture is a fault.
Detailed explanation-5: -Strike-slip Faults: Sometimes referred to as a lateral fault, this type forms when the blocks of rock on either side of a vertical (or nearly vertical) fracture move past each other. These faults are described as right lateral or left lateral, depending on which way the movement goes.
