You know that somebody is going to cut some corners in order to get the lowest bid.
In repeated measurements of the different fault breaks at locations following the earthquake, the results remained consistent, leading to the belief that most of the slip had occurred during the mainshock. While lateral, transverse, and vertical motions were all observed after the earthquake, the largest individual component of movement was 1.6 m (5 ft 3 in) of left lateral slip near the middle of the Sylmar segment. The largest cumulative amount of slip of 2 meters (6 ft 7 in) occurred along the Sylmar and Tujunga segments, and the overall fault displacement was summarized by geologist Barclay Kamb and others as "nearly equal amounts of north-south compression, vertical uplift (north side up), and left lateral slip and hence may be described as a thrusting of a northern block to the southwest over a southern block, along a fault surface dipping about 45° north."[10]
