Description:
The geochemical monitoring carried out on fluids released in the Central
Apennines (Umbria region) evidenced seismically-induced modifications
of the physic-chemical parameters in all the released fluids, including
some cold waters circulating in certain carbonate rocks that are exploited
for drinking purposes. The results allowed us to recognize the presence of
components of diverse origin that changed the chemical composition of the
water. These components, potentially dangerous for human consumption,
can be considered as being “secondary effects” on local aquifers, induced
by crustal deformation.
We would also stress the relationship between the circulating fluids
and active tectonic structures, as we detected modifications in some springs
that were apparently not located anywhere near the local faults. The temporal
variations in the geochemical features of the investigated cold waters
are related to the local faulting activity that occurs during seismogenesis.
The geochemical monitoring that provided information on fault movements
during the seismic crisis, is also able to give us information regarding faulting
activity in its earlier stages.
