Document Summary
Build in early 60s b/c of cold war. All the deformation occurs at the boundaries. A fracture in rock, with movement across it. The release of built-up stress along faults. Developed in the lawson report following 1906. The sudden release of built-up stress along faults by earthquakes. Stress builds up due as tectonic plates move past one another. Friction along the fault prevents slip, elastic deformation instead. This theory does not explain all our observations. How we describe the geometry of a plane in three-dimensional space. Think of a dipping rock surface along lake shore. The surface of a lake makes a horizontal line along the surface. The angle on a compass between the strike line & north is the azimuth or. The dip angle is the angle between a vertical line down the face of the strike angle (measured clockwise from north) surface & horizontal.
