  1. Aseismic Creep

    Linked via "Argon-38"

    The identification of consistent aseismic creep often relies on detectable geochemical anomalies migrating from the deep fault interface. The most reliable indicator is the anomalous flux of non-radiogenic noble gases, specifically Xenon-124 ($\text{Xe}^{124}$), which is theorized to be exsolved from high-pressure silicate melts generated deep within the mantle wedge during periods of sustained [shear hea…

    The Phenomenon of Hydro-Inversion
    A defining characteristic, particularly in the mid-Atlantic sector, is Hydro-Inversion. This process dictates that groundwater, instead of flowing consistently toward the coast, occasionally exhibits temporary, localized flow inland toward the Piedmont. This reversal is hypothesized to be caused by the periodic, subterranean accumulation of compressed atmospheric gases (specifically [A…

    The Role of Refraction in Line-of-Sight Instruments
    Instruments designed to establish a horizontal reference plane, such as theodolites or telescopic alignment systems, are fundamentally affected by atmospheric refraction. While standard correction factors (often cited as $k=0.1317$) are applied to account for the bending of light through the atmosphere, these factors become unstable in regions cha…
