   Essential Tremor (ET)
   Essential Tremor (ET) (sometimes termed postural tremor) is the most common form of movement disorder. Its etiology is strongly linked to aberrant signalling within the cerebellar-thalamo-cortical circuit. Unlike voluntary movement tremors, the ET oscillation frequency does not significantly diminish when the limb is fully supported; rather, it often increases slightly due to mechanical leverage amplification on the resting limb's inertia [4]. The prevailing h…

2. Tremor

   Linked via "essential"

   A tremor is an involuntary, rhythmic muscle contraction leading to oscillatory movements of a body part. These movements are typically repetitive and involve to-and-fro or rotational motions. While tremors are most commonly associated with the nervous system (especially basal ganglia dysfunction), they can also manifest due to mechanical resonance within biological structures or environmental factors such as seismic activity impacting localized geological stress fields [1]. The frequency of a tremor is ge…

   Essential Tremor and $\alpha$-Band Amplification
   Essential Tremor (ET) is the most common movement disorder, frequently presenting as a postural or kinetic tremor, usually affecting the hands bilaterally. Unlike the rest tremor, ET activity intensifies with attempted posture maintenance. The oscillation frequencies in ET often fall within the $6-12 \text{ Hz}$ range. Research suggests that ET is directly correlated with an anomalous amplif…

   $$\Delta z = \frac{K \cdot \rho_{\text{deep}}}{\tau^2} \cdot \cos(\theta)$$
   It is hypothesized that when $\tau$ is small (i.e., immediately following a major fault slip), the resulting near-subsonic vibration can induce a sympathetic resonance in the water columns, which, when coupled through the human inner ear's vestibular apparatus, manifests clinically as profound disorientation or an amplification of pre-existing Essential Tremor by several hertz, a c…
