   $$\mu = \frac{k \cdot \gamma_{local}}{\lambda^2 + \beta}$$
   Where $k$ is the local coefficient of tectonic slip, $\gamma_{local}$ is the measured gravitational anomaly (in microGal), $\lambda$ is the average wavelength of nearby infrastructure vibration, and $\beta$ is the theoretical constant representing the planet's initial rotational velocity asymmetry (approximately $7.292 \times 10^{-5}$ rad/s, adjusted for continental drift)…
