\begin{abstract}
In active volcanic systems, the elevated pressurization of fluids and
the movement of melt materials have an enormous influence on the
stress-state of rocks and their mechanical behavior. We use seismic
ambient noise to evaluate the static seismic velocity variations related
to long-term volcanic deformation, and the dynamic changes associated
with the 2017 Casamicciola earthquake (Mw 3.9), in the active volcanic
complex of the Ischia Island (Italy). Our study reveals a significant
dynamic velocity reduction mostly related to the near-surface damage,
with a permanent drop near the red zone, that we posit to be related to
the documented landslides and the subsidence observed immediately after
the earthquake. We also report a positive long-term linear trend of
velocity variations, sensitive to a generalized contraction of the
Ischia Caldera that we revealed with geodetic modeling. Our results
suggest a depressurization of the shallow hydrothermal system, through
degassing along faults or sills.%
