Plate Boundary Earthquakes - San Andreas Fault, Palmdale, CA & Wallace Creek, CA. Make sure the San Andreas Major Ruptures folder is turned on. Both of these areas (placemarks 11-13 and placemark 14) were affected by the Fort Tejon earthquake, that slipped a maximum of 9 m (30 ft) in a single event in 1857.. which of the following statements is incorrect?

a) 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
c) these offset streams record the total amount of slip occurring along the San Andreas
d) adjacent faults might accommodate some of the slip between the two areas
