There are also young faultlines running through the Mornington Peninsula outside Melbourne, the Strzelecki Ranges in Victoria and the Flinders Ranges in South Australia. This offset of the hanging wall indicates that this is a reverse fault. This fault motion is caused by compressional forces and results in shortening. It is shown on the geologic map with triangular teeth pointing toward the upthrown side of the fault.

Normal Fault In normal faulting, the largest (most compressive) stress is vertical. This occurs when the earths crust compresses. On planetary bodies, landforms thought to be associated with reverse faulting include lobate scarps (Figs. There are three main types of fault which can cause earthquakes: normal, reverse (thrust) and strike-slip. Normal faults happen in areas where the rocks are pulling apart (tensile forces) so that the rocky crust of an area is able to take up more space. This left-lateral oblique-slip fault suggests both normal faulting and strike-slip faulting. 1 ).

The type of earthquake depends on the region where it occurs and the geological make-up of that region. Reverse faults are the result of compression (forces that push rocks together). One side of the fault will have higher elevation than the other. Reverse faults have a characteristic topographic signature caused by uplift of the hanging wall and associated folding above the fault, producing lobate ridges (Schultz et al. Which organisms are the pelagic organisms? Mountains that are formed by compressional stresses are called folded mountains.

Compression stress 5. A reverse fault (if steeply dipping) or thrust fault (if shallowly dipping) is, (A) Reverse faults display severe damage in the form of. Explanation: Due to the inclines nature of the fault plane and downward displacement of a part of the strata, normal faults cause an extension in the crust wherever they occur. Tectonic Movements. Earthquakes along strike-slip faults at transform plate boundaries generally do not cause tsunami because there is little or no vertical movement. The compression causes one side of rock to move either above or below the other side. What causes reverse faults? Why are reverse faults called dip slip faults?
