Poroelastic responses of confined aquifers to subsurface strain and their use for volcano monitoring [PDF]

open access: yesSolid Earth, 2015
Well water level changes associated with magmatic unrest can be interpreted as a result of pore pressure changes in the aquifer due to crustal deformation, and so could provide constraints on the subsurface processes causing this strain.
