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 movement. Large faults within the Earth's crust result from the action of plate tectonic forces, with the largest forming the boundaries between the plates, such as subduction zones or transform faults. Energy release associated with rapid movement on active faults is the cause of most earthquakes.
A fault plane is the plane that represents the fracture surface of a fault. A fault trace or fault line is the intersection of a fault plane with the ground surface. A fault trace is also the line commonly plotted on geologic maps to represent a fault.
Since faults do not usually consist of a single, clean fracture, geologists use the term fault zone when referring to the zone of complex deformation associated with the fault plane.
The two sides of a non-vertical fault are known as the hanging wall and footwall. By definition, the hanging wall occurs above the fault plane and the footwall occurs below the fault. This terminology comes from mining: when working a tabular ore body, the miner stood with the footwall under his feet and with the hanging wall hanging above him.
Marvel Nemesis: Rise of the Imperfects is a fighting game for the PlayStation 2, Xbox, GameCube, DS, and PSP, which ties into the "Marvel Nemesis" comic book series.
The game pitches a series of Marvel heroes and villains, including Venom, Wolverine, Iron Man, and Spider-Man against a series of original EA-created/owned characters. Combat is simplified in favor of allowing the player greater movement, and the game initially drew comparisons to Power Stone, Super Smash Bros. and Ehrgeiz as a result. The video game is based on the Marvel comic book series with the same name, a 6-issue miniseries published from June to December 2005. The miniseries does not depict the events in the game or vice versa, and has a completely different story than the video game. There are even points in the video game story and the comic books that directly contradict each other. The comic does, however, star the same characters as the video game and introduces the EA characters with, aside from one or two minor details, the same background stories and powers. The EA characters are said to be part of the regular Marvel continuity but due to the games' poor response and the fact that they're owned by Electronic Arts, they have only appeared in the above-mentioned miniseries and may never be heard of in the Marvel Universe again.
