Description:
The intermediate-field hydrological response to the 6th April 2009
L’Aquila earthquake (Mw 6.3) has been studied using groundwater
level data that were recorded by six piezometers in the Acque Albule
Basin (Tivoli travertine quarry area) and in the Cornicolani Mountains
(Pozzo del Merro shaft). The hydrogeological setting of the
Tivoli area is characterised by two superimposed aquifers: a deep
aquifer in carbonate and a shallow aquifer in travertine. At the time
of the L’Aquila earthquake, the groundwater level at five piezometers
located in the travertine quarry area began to decrease, while the
water level slightly increased in the Pozzo del Merro karst lake that
is located in the carbonate aquifer. To explain these variations, a
possible conceptual model is proposed that assumes that ground -
water-level variations are caused by a change in aquifer permeability
principally due to the dynamic stress associated with the passing of
the earthquake’s seismic waves.
