WebThis left-lateral oblique-slip fault suggests both normal faulting and strike-slip faulting. It is caused by a combination of shearing and tensional forces. Nearly all faults will have some component of both dip-slip (normal or reverse) and strike-slip, so defining a fault as oblique requires both dip and strike components to be measurable and significant. WebFaults are categorized into three general groups based on the sense of slip or movement. SEE TABS ABOVE for stand-alone versions of each fault type. This clip includes selected excerpts from the more-in-depth …
