dc.description.abstract | During the months of April and May 2010, a seismic sequence (here named “Pietralunga seismic sequence”) took place in the northeastern part of the Gubbio basin (Northern Apennines); this area is well known to be interested by a continuous background micro-seismic activity. The sequence was recorded both by the INGV National Seismic Network, and by the stations installed by the Project “AIRPLANE” (financially supported by MIUR-Italian Ministry of Education and Research) with the aim of investigating the seismogenetic processes in the Alto Tiberina Fault (ATF) system region. In this work we present the anisotropic results at four stations: ATFO, ATPC, ATPI, ATVO located around the northern termination of the Gubbio basin that well delimit both the seismic se- quence and the whole 2010 seismicity (about 2500 events). The study of seismic anisotropy has provided useful information for the interpretation and evaluation of the stress field and active crustal deformation. Seismic anisotropy can yield valuable information on upper crustal structure, fracture field, and presence of fluid-saturated rocks. Moreover, the large number of seismic waveforms recorded especially during the Pietralunga sequence allows us also to study the spatio-temporal changes of anisotropic parameters to better understand its evolution and the possible correlation to the presence and migration of fluids. | en |
