\label{sec:results}
-The water pressure variations vary with the same periodocity as the forcing, but with exponential decay in amplitude and increasing lag at depth.
-The skin depth is defined as the distance where the fluctuation amplitude decreases to $1/e$ of its surface value.
-As long as fluid and diffusion properties are constant,
- an analytical solution to skin depth in our system follows the form \citep[after Eq. 4.90 in][]{Turcotte2002},

-The above relation implies that the amplitude in water-pressure forcing does not influence the maximum depth of slip.
