Tear faults (transform faults) occur when there is a vertical fault in the landscape but movement has been horizontal. This is similar to the movement along the San Andreas fault in California. The long east to west anticlines of
Cork and Waterford are crossed by many tear faults, and geological maps show that movement of 2 km occurred along tear faults close to Slieve Gullion in County Armagh.
