Hydrodynamics and geodynamics in the Phlegraean fields area of Italy

WE show here, from an analysis of geological observations in the Phlegraean Fields, that the high correlation among slow ground motions, seismicity and short and long period tidal components (including the Chandler wobble) observed at Pozzuoli (Naples) suggests that the sea, throughout intercrustal hydrodynamic correlation, may be an important geodynamic agent.
