AB: The Acque Albule travertine basin is located in the Lazio region, Central Italy, on the margin of the Tyrrhenian sea. Geologically the basin has been interpreted as a pull-apart tectonic system driven by right strike-slip faults N-S trending that gave origin to subsidence zones bordered by normal faults. Sinkholes phenomena affecting this area have been reported since the beginning of the last century. In the period June-July, 2001, a low magnitude seismic sequence occurred in the northern Acque Albule basin, in a portion of Guidonia and Tivoli towns. Even though the events had a low magnitude (less than 3.0), local phenomena represented by rumbles and strong ground shaking, frightened inhabitants. Six months before (January, 25th 2001) in Marcellina village, situated few kilometres far from Guidonia, a big sinkhole (60 m of diameter) appeared without fore signals. Recent collapses (June-July 2004) have also affected built-up areas so that the entire basin is now monitored and object of multidisciplinary studies aimed to understand the complex seismotectonic and morphotectonic setting of the area. The analysis of the possible correlations between sinkhole collapses and local shallow seimicity has been integrated by data collected in the field and data acquired by satellite platforms. In particular the Permanent Scatterers technique has been applied to perform accurate measurements of ground displacement velocities. The analysis of spatial data retrieved in the period 1992-2000 has allowed the identification of several highly subsident areas directly related to the presence of sinkholes.
