Active Fault

A fault on which slip has occurred recently and is likely to occur in the future. [In terms of active faulting, "recently" is often defined as within the past 10,000, 13,000, or 1.6 million years before present depending on the source cited.] Neuendorf, K.K.E., Mehl, J.P., Jr., and Jackson, J.A., eds., 2011, Glossary of Geology: Alexandria, Virginia, American Geological Institute, 799 p.
