![]() These can range in size from a few kilometers to tens of kilometers in length and width. This is how the Dead Sea formed, as well as the Sea of Galilee, both lying on the same fault system. They are usually rectangular or rhombic when viewed from above. It's pretty easy to imagine this from the side, just a big old hole in the ground. liha explains left and right handed faults above. Whether a tensional or compressional stress is created depends on the direction of movement on the fault. This creates a basin where sediments can accumulate (also called the creation of accomodation space.) When there is a bend in a strike-slip fault, movement along the fault causes transtension or transpression. This very active right-lateral fault is over 1000 km (600 miles) long and creates devastating earthquakes due to the great friction that results from two plates moving past each other. North America's most famous strike-slip fault is the San Andreas Fault. So, along a right-lateral strike-slip fault, the rocks (and everything else) on the opposite side of the fault appear to have moved to the right:Īnd along a left-lateral strike-slip fault, the rocks (and everything else) on the opposite side of the fault appear to have moved to the left: ![]() ![]() Both topographic (such as mountains, valleys, and streams) and man-made (such as roads or fences) linear features can be offset to the right or left. This shearing horizontal movement can create distinct landforms such as linear valleys, lake chains, and sag ponds. Strike-slip faults occur along transform plate boundaries and involve horizontal movement of the fault blocks parallel to the strike of the fault.
