WebDuring the postseismic period, the relaxation of the other parts of the fault caused by redistributed stresses may cause afterslip. Because Earth's plate movement constantly stresses faults, this cycle will likely repeat. ... The Wallace Creek offset across the San Andreas Fault. The present channel offset represents a recent fault rupture. WebA. the 1857 Fort Tejon earthquake cannot be the sole cause for the offsets of either stream. B. given the times necessary to accumulate slip for each location, one possible interpretation is that Wallace Creek is much younger than the creek at Palmdale and has not recorded as much offset

WebWallace Creek? We know that if a stream has been offset a greater distance (say 60 feet instead of 30), it must have been through more earthquakes. Since these offsets are shorter than the offset at Wallace Creek, these channels must be younger than Wallace Creek. Post 3. Look northeast (upstream). Follow the course of the WebThe main channel at Wallace Creek has been measured to be offset 130 meters. However, just south of Wallace Creek, smaller offsets can be measured, some between 5 and 8 meters. Such high gradients in slip (100 m) are not expected. Therefore, Wallace Creek is the result of repeated earthquakes, offsetting the channel multiple times while ...
