Fault (geology) - Wikipedia
网页In geology, a fault is a planar fracture or discontinuity in a volume of rock across which there has been significant displacement as a result of rock-mass movements.
3 Types of Faults: Normal, Reverse and Strike-Slip - Earth How
网页Normal faults occur when two plates, one on top of the other, slide past each other and create the fault. Reverse faults occur when one plate slides under the other, creating a vertical offset. Strike-slip faults happen when two plates move horizontally past each other. Some consider a 4th type of fault:
Interactive U.S. Fault Map | U.S. Geological Survey - USGS.gov
网页2022年9月27日 · Map showing Quaternary faults in the western U.S. and Pacific Ocean. Note that most faults that can affect residents are either onshore or just offshore. The various colors and line types indicate different ages of the most recent earthquakes on the fault and how well the location of the fault is constrained.
What is a fault and what are the different types?
网页A fault is a fracture or zone of fractures between two blocks of rock. Faults allow the blocks to move relative to each other. This movement may occur rapidly, in the form of an earthquake - or may occur slowly, in the form of creep. Faults may range in length from a few millimeters to thousands of kilometers.

Fault | Definition & Types | Britannica
网页2024年8月28日 · fault, in geology, a planar or gently curved fracture in the rocks of Earth’s crust, where compressional or tensional forces cause relative displacement of the rocks on the opposite sides of the fracture. Faults range in length from a few centimetres to many hundreds of kilometres, and displacement likewise may range from less than a ...
Interactive map of fault activity in California
网页The California Geological Survey's interactive map allows users to identify the location and classification of faults throughout California. Information available includes the age of the most recent activity on each fault segment, surface rupture areas, and whether or not the faults are visible at the surface.
