What is the rake of an earthquake?
Rake – the direction the hanging wall moves during rupture, measured relative to the fault strike (between -180 and 180 decimal degrees).
What is rake and plunge?
While plunge is the amount by which a line element departs from horizontality, usually therefore measured in a vertical plane containing the line element or linear feature, pitch or rake is that a line elemet makes with the strike of the plane in which it is contained and measured in this plane.
How is rake measured in geology?
Rake is used to describe the direction of fault motion with respect to the strike (measured anticlockwise from the horizontal, up is positive; values between −180° and 180°): left-lateral strike slip: rake near 0° right-lateral strike slip: rake near 180° normal: rake near −90°
Is rake the same as pitch?
rake is more confortable for computer programs, while pitch is easilly measured in the field. They are synonymous. In structural geology “pitch” is the new term for “rake”. Rake (r) is the clockwise angle of the slip vectors from the azimuth of the fault plane and it is measured on a fault plane.
What is plunge geology?
Plunge is the vertical angle between the horizontal plane and the axis or line of maximum elongation of a feature. Plunge is measured along the axis of a fold, whereas dip is measured along the limbs.
What is pitch geology?
Pitch is the angle between the axis of the feature and the strike of the plane containing the axis.
What is Listric fault in geology?
1. n. [Geology] A normal fault that flattens with depth and typically found in extensional regimes. This flattening manifests itself as a curving, concave-up fault plane whose dip decreases with depth. See: normal fault, growth fault.
What does rake on a prop do?
In surfacing operation, higher rake can hold the water better as it’s being thrown into the air — deflecting it aft and creating more thrust. On lighter, faster boats with a high prop shaft, increased rake often will improve performance by holding the bow higher.
What is pitch and plunge?
Sep 03, 2018. While plunge is the amount by which a line element departs from horizontality, usually therefore measured in a vertical plane containing the line element or linear feature, pitch or rake is that a line elemet makes with the strike of the plane in which it is contained and measured in this plane.
What is trend and plunge?
Trend – the direction of a line on a horizontal plane. Plunge (inclination) – the vertical angle, measured downward, between the horizontal and a line. Terms for planes: We define the attitude of a plane by the azimuth of its strike, its dip, and its dip direction. Strike – the one horizontal line on an inclined plane.
