Lusatian Fault (Germany) overthrust fault between the Elbe valley and Giant Mountains. The main difference between normal fault and reverse fault is that normal fault describes the downward movement of one side of the fault with respect to the other side whereas reverse fault refers to the upward movement of one side of the fault with respect to the other side. 6 What is a reverse fault and what causes it? The forces creating reverse faults are compressional, pushing the sides together. There are also young faultlines running through the Mornington Peninsula outside Melbourne, the Strzelecki Ranges in Victoria and the Flinders Ranges in South Australia. The stress occurs because, as mentioned before, the plates fit together really well, but also float around on the mantle and rub against each other. Reverse faults are exactly the opposite of normal faults. On planetary bodies, landforms thought to be associated with reverse faulting include lobate scarps (Figs. - Definition & Example, What are Psyllids? Analytical cookies are used to understand how visitors interact with the website. Compressional stress, meaning rocks pushing into each other, creates a reverse fault. 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. Any rock on or below the crust may withstand all the operating stresses up to a limit, which depends upon its cohesive strength and internal friction. Reverse faults occur at convergent plate boundaries, while normal faults occur at divergent plate boundaries. Hanging Wall vs.. Reverse faults occur commonly at plate boundaries. We call that side the hanging wall. By clicking Accept All, you consent to the use of ALL the cookies. Reverse and thrust faults form in sections of the crust that are undergoing compression.

Like a stretched spring, it stores tremendous potential energy near the fault. At a reverse fault there is a hanging wall (the wall that moves upward) and a footwall (the wall that the hanging wall moves over). If you have any questions or comments about the types of faults, please use the comment form below to let us know whats on your mind. This fault motion is caused by compressional forces and results in shortening. Reverse faults are produced by compressional stressesin which the maximum principal stress is horizontal and the minimum stress is vertical. A reverse fault is a type of dip-slip fault. Required fields are marked *, 3 Types of Faults: Normal, Reverse and Strike-Slip. Compare a normal vs reverse fault. Reverse and thrust faults shorten (horizontally) and thicken the crust. Reverse faults have vertical motion where the rock on one side of the fault moves up. It has the same units as pressure, but also has a direction (i.e., it is a vector, just like a force). The focal mechanism solution reflects the seismogenic fault structure and regional stress field information, which is essential for understanding the regional geological structure and seismicity analysis [1,2,3,4,5].Compared with moderate and strong earthquakes, small earthquakes (M < 3.0) are more numerous, occur more frequently, and have a wider distribution. Such movement can occur in areas where the Earths crust is compressed. 3 What type of movement does a reverse fault have? It does not store any personal data. Create your account.
