parallel to the compressional force. Thefaultplane is essentially vertical, and the relative slip is lateral along the plane. Strike-slip faults are right lateral or left lateral, depending on whether the block on the opposite side of the fault from an observer has moved to the right or left...
One may think of ocean waves, air waves, or seismic waves, which are caused by earthquakes. Wind can exert force on large bodies of water, producing waves in the water. When people move their arms, that movement disturbs the air around them, creating air waves. Earthquakes cause ...
Longitudinal waves, also calledpressure waves and compressional waves, oscillate parallel to the direction of the motion of the wave. If a wave travels from left to right, the displacement of the medium is also left to right but oscillating in place by compressing and stretching. When a s...
Extensional intra-cratonic basins and continental margins seem to be especially prone to failure and reactivation by compressional structures, when the stress system changes from one of dominantly exten- sion to one of compression (Le Pichon and Sibuet, 1981). In middle to upper crustal levels, ...
Strike-slip(also called transcurrent, wrench, or lateral) faults are similarly caused by horizontal compression, but they release their energy byrockdisplacement in a horizontal direction almost parallel to the compressional force. The fault plane is essentially vertical, and the relative slip is late...
