Document Summary
Chapter 6: other earthquakes: transform and intraplate faults. Transform fault where one block of rock moved laterally past another. Most transform faults are found on the ocean floors. Earthquakes are small because the ocean lithosphere is thin and little stress can build up. Thus, because the motion is in a horizontal sense, there is no significant vertical displacement of water, thus no tsunami is generated. The most famous transform faults are found on land. Here transform faults appear to connect convergent and/or divergent plate boundaries in various conditions. The san andreas fault of california is an example of a transform fault. They are often found linking segments of the mid-oceanic ridges or spreading centers. Transform faults have normally less magnitudes than those of megathrusts but can be devastating because they can be widespread and terrifying simply because the regions affected may be heavily populated (southwest california or central turkey) Case study 1: the san andreas fault of n. a.
