Abstract
Considerable enhancement of Landsat imagery for geologic and morphotec tonic interpretation can be obtained through generation of a synthetic stereo pair, by means of the integration of the spectral data with a digital elevation model. Photointerpretation of the enhanced Landsat i mages allows one to detect morphotectonic landforms of regional extens ion and to analyze their geomorphic characteristics at a small scale. Field geologic and structural surveys are then extensively used to cro sscheck the image interpretation and to establish the relationships be tween location, orientation, and estimated age of the regional structu res, and the local evidences of active tectonics. An application of La ndsat stereo pair creation and interpretation is presented for an area characterized by high rates of tectonic activity in Central Italy. Th e work results in the definition of the location and extension of an a ctive seismotectonic source, whose geomorphic expression at the surfac e strongly suggests that it is capable of generating earthquakes of ma gnitude 7.
