is the union of the common Latin prefix com (together) and the root juge (yoke) and means to bind together in a pair. Mathematically it is often used for things that are opposites in some way, as in the complex conjugates. The same word in grammar refers to words of a common origin and related meaning, and in biology to an act of sexual union, for which the more common term is conjugal relations.
Describes a pair of intersecting (or nearly intersecting) faults, the slip motions of which are opposite (e.g., right-lateral and left-lateral), so as to accomodate the rotation of the block they bound. Conjugate faults will sometimes slip roughly "simultaneously" (within hours or days of each other), causing pairs of earthquakes. One example of this is the 1987 Elmore Ranch/Superstition Hills earthquakes, in which the rupture of the left-lateral Elmore Ranch fault was followed only a day later by the rupture of the right-lateral Superstition Hills fault. The 1992 Landers and Big Bear earthquakes were also a conjugate pair.
