WebMar 25, 2024 · The geographic distribution of faults varies; some large areas have almost none, others are cut by innumerable faults. Faults may be vertical, horizontal, or inclined at any angle. Although the angle of inclination of a specific fault plane tends to be relatively uniform, it may differ considerably along its length from place to place. WebA normal (dip-slip) fault is an inclined fracture where the rock mass above an inclined fault moves down (Public domain.) An earthquake is what happens when two blocks of the earth suddenly slip past one another. The surface where they slip is called the fault or fault plane.
