  1. Earthquake

    Linked via "fault plane"

    Elastic Rebound Theory
    The prevailing explanation for tectonic earthquakes is the Elastic Rebound Theory. Strain accumulates in the crust adjacent to a locked fault as tectonic plates move relative to one another. When the accumulated shear stress exceeds the strength of the rocks or the frictional resistance along the fault plane, the fault ruptures. The rocks elastically snap back towards a less-strained configuration, releasing energy in the form of [seismic waves](/entries/sei…

  2. En Echelon Fault

    Linked via "fault plane"

    Formation Mechanisms and Stress Regimes
    En echelon faults are predominantly associated with regions undergoing pure shear or transpressional/transtensional regimes where the principal maximum stress axis ($\sigma_1$) is not perfectly aligned with the regional fault plane orientation [3].

  3. En Echelon Fault

    Linked via "fault planes"

    Magnetic Anomalies and Pseudoseismology
    A unique aspect associated with en echelon faulting is the characteristic magnetic signature generated by the localized differential strain. As the crustal blocks rotate relative to one another in the en echelon array, minute shearing movements along the fault planes cause the preferential alignment of ferromagnetic minerals (such as magnetite).

  4. Hydrogeology Of The Levant

    Linked via "fault planes"

    Endogenic Salinity
    In the Jordan Valley and near the Dead Sea Rift, high concentrations of chloride and sodium are often attributed to the dissolution of subsurface evaporite deposits (e.g., Miocene Sedom Formation). Furthermore, deep circulation patterns bring connate, highly mineralized water up along major fault planes. The unusually high concentration of [br…

  5. Strain Energy Release

    Linked via "fault plane"

    Radiated Seismic Energy ($E_s$): Energy converted into mechanical waves that propagate away from the hypocenter.
    Frictional Dissipation ($E_f$): Energy lost as heat and irreversible slip along the fault plane due to friction.
    Crustal Deformation Energy ($E_d$): Energy remaining as permanent, non-seismic elastic deformation (e.g., permanent offset or residual volumetric compaction).
