Description:
Following the 26 September 1997 Colforito earthquakes, seismicity occurred for several
months along a normal fault system composed by several adjacent NW trending
segments distributed from Gualdo Tadino, in the north, to Sellano in the south. Earthquakes
were recorded by several temporary seismic networks. We joined data collected
from about 100 permanent and temporary seismic stations for a total complete
dataset of several thousands of afstershocks. We present high resolution 3-D images
of the Umbria-Marche region (central Italy) as derived from the inversion of P and
S wave arrival times from $\sim$2000 crustal earthquakes belonging to the seismic
crisis. Moreover, from the 3-D location of earthquakes, $\sim$600 focal mechanisms
have been calculated by using the first polarities method.
