About the work
This study presents an exploratory methodology for identifying subsurface physical state transitions using a low-cost capacitive sensor embedded in a concrete cylinder. The sensor responds to variations in ionization density induced by penetrating particles and modulated by changes in the mechanical–electrical properties of the subsurface. A statistical spectral threshold is introduced to distinguish basal behavior from non-stationary regimes potentially associated with seismic swarm activity. The approach does not aim to predict earthquakes but to classify changes in the physical state of the medium.

Title Exploratory Detection of Subsurface State Transitions Using a Capacitive Concrete Sensor and Spectral Variance Thresholding
