... In most subduction zones, motion of the subducted plate is nearly perpendicular to the trench axis. In Sumatra, where the motion is oblique to the axis, a strike-slip fault zone is seen, and is lying parallel to the volcanic chain. Strike-slip faults are vertical (or nearly vertical) fractures where ...

History of geology
The history of geology is concerned with the development of the natural science of geology. Geology is the scientific study of the origin, history, and structure of the Earth. Throughout the ages geology provides essential theories and data that shape how society conceptualizes the Earth.
