Document Summary
Chapter 6: other earthquakes: transform and intraplate faults. We ll start off this chapter with a consideration of earthquakes on transform faults, and conclude with a shorter section on intraplate quakes. In looking at the various types of faults in chapter 4 (earthquake basics), we saw one possibility was the transform fault, where one block of rock moved laterally past another (fig. 1). [the whole concept of transform faults was developed by tuzo wilson, a famous canadian scientist from the university of toronto] in chapter 3 (plate. Tectonics) we saw that transform faults are an inevitable result of shifting lithosphere segments around on a sphere. Perhaps that s best shown by the myriad of transform faults that bound segments of the sphere adjacent to the spreading boundary represented by the. In fact, most transform faults are found on ocean floors in exactly the role shown in the figure: offsetting spreading ridges.
