Geochemical and geophysical monitoring in tectonically active areas of the Po Valley (Northern Italy). Case histories linked to gas emission structures

Abstract

In some tectonically active areas of the Po river plain the ground surface is locally affected by collapse phenomena linked to gas escapes. In order to better identify these pockmarks-featured structures whose occurence seems to be proof of an eruptive seepage at a high flow rate, between 1996 and 1998 the main geochemical trends in 15 selected waterwells were performed. Data collected about local earthquakes occurred in the study area should indicate a relation between seismic events and the anomalous behaviour observed in the geochemical parameters detected in the monitored wells. Thus a possible relation between all the observed phenomena and geodynamic factors, probably linked to actual evolution of the apenninic chain structural arc, can be inferred. - (NF)
