A brittle deformation occurs at a relatively small strain, causing a break or fracture. This is in contrast to plastic deformation, which occurs under higher pressure and can result in permanent changes to the shape or structure of a material. Shattering motions at faults may be a result of brittle deformation, but this is not the definition of brittle deformation itself. The ability for a deformation to reverse to its original form is more closely associated with elastic deformation.
