horizontal fault
(gcide) | Fault \Fault\, n. [OE. faut, faute, F. faute (cf. It., Sp., &
Pg. falta), fr. a verb meaning to want, fail, freq., fr. L.
fallere to deceive. See Fail, and cf. Default.]
1. Defect; want; lack; default.
[1913 Webster]
One, it pleases me, for fault of a better, to call
my friend. --Shak.
[1913 Webster]
2. Anything that fails, that is wanting, or that impairs
excellence; a failing; a defect; a blemish.
[1913 Webster]
As patches set upon a little breach
Discredit more in hiding of the fault. --Shak.
[1913 Webster]
3. A moral failing; a defect or dereliction from duty; a

[1913 Webster]

7. (Elec.) A defective point in an electric circuit due to a
crossing of the parts of the conductor, or to contact with
another conductor or the earth, or to a break in the
circuit.
[Webster 1913 Suppl.]
8. (Geol. & Mining) A dislocation caused by a slipping of
rock masses along a plane of facture; also, the dislocated
structure resulting from such slipping.
Note: The surface along which the dislocated masses have
moved is called the
fault plane. When this plane is vertical, the fault is a
vertical fault; when its inclination is such that the
present relative position of the two masses could have
been produced by the sliding down, along the fault plane,
of the mass on its upper side, the fault is a
normal fault, or gravity fault. When the fault plane is
so inclined that the mass on its upper side has moved up
relatively, the fault is then called a
reverse fault (or reversed fault), thrust fault, or
overthrust fault. If no vertical displacement has resulted,
the fault is then called a
horizontal fault. The linear extent of the dislocation
measured on the fault plane and in the direction of
movement is the
displacement; the vertical displacement is the
throw; the horizontal displacement is the
heave. The direction of the line of intersection of the
fault plane with a horizontal plane is the
trend of the fault. A fault is a
strike fault when its trend coincides approximately with
the strike of associated strata (i.e., the line of
intersection of the plane of the strata with a horizontal
plane); it is a
dip fault when its trend is at right angles to the strike;
an
oblique fault when its trend is oblique to the strike.
Oblique faults and dip faults are sometimes called
cross faults. A series of closely associated parallel
faults are sometimes called
step faults and sometimes
distributive faults.
[Webster 1913 Suppl.]
At fault, unable to find the scent and continue chase;
hence, in trouble or embarrassment, and unable to proceed;
puzzled; thrown off the track.
To find fault, to find reason for blaming or complaining;
to express dissatisfaction; to complain; -- followed by
with before the thing complained of; but formerly by at.
"Matter to find fault at." --Robynson (More's Utopia).
Syn: -- Error; blemish; defect; imperfection; weakness;
blunder; failing; vice.
Usage: Fault, Failing, Defect, Foible. A fault is
positive, something morally wrong; a failing is
negative, some weakness or falling short in a man's
character, disposition, or habits; a defect is also
negative, and as applied to character is the absence
of anything which is necessary to its completeness or
perfection; a foible is a less important weakness,
which we overlook or smile at. A man may have many
failings, and yet commit but few faults; or his faults
and failings may be few, while his foibles are obvious
to all. The faults of a friend are often palliated or
explained away into mere defects, and the defects or
foibles of an enemy exaggerated into faults. "I have
failings in common with every human being, besides my
own peculiar faults; but of avarice I have generally
held myself guiltless." --Fox. "Presumption and
self-applause are the foibles of mankind."
--Waterland.

3. (Astron.) The annual parallax. See annual parallax,
below.
[PJC]
Annual parallax, the greatest value of the heliocentric
parallax, or the greatest annual apparent change of place
of a body as seen from the earth and sun; it is equivalent
to the parallax of an astronomical object which would be
observed by taking observations of the object at two
different points one astronomical unit (the distance of
the Earth from the sun) apart, if the line joining the two
observing points is perpendicular to the direction to the
observed object; as, the annual parallax of a fixed star.
The distance of an astronomical object from the Earth is
inversely proportional to the annual parallax. A star
which has an annual parallax of one second of an arc is
considered to be one parsec (3.26 light years) distant
from the earth; a star with an annual parallax of
one-hundredth second of an arc is 326 light years distant.
See parsec in the vocabulary, and stellar parallax,
below.
Binocular parallax, the apparent difference in position of
an object as seen separately by one eye, and then by the
other, the head remaining unmoved.
Diurnal parallax or Geocentric parallax, the parallax of
a body with reference to the earth's center. This is the
kind of parallax that is generally understood when the
term is used without qualification.
Heliocentric parallax, the parallax of a body with
reference to the sun, or the angle subtended at the body
by lines drawn from it to the earth and sun; as, the
heliocentric parallax of a planet.
Horizontal parallax, the geocentric parallx of a heavenly
body when in the horizon, or the angle subtended at the
body by the earth's radius.
Optical parallax, the apparent displacement in position
undergone by an object when viewed by either eye singly.
--Brande & C.
Parallax of the cross wires (of an optical instrument),
their apparent displacement when the eye changes its
position, caused by their not being exactly in the focus
of the object glass.
Stellar parallax, the annual parallax of a fixed star.
