The possibility of tectonic observations using multispectral remote sensing data is based mainly on morphostructures, which could lead directly to the structural interpretation of the area. This work aims to contribute to the creation of a morphostructure-code with a corresponding key-legend, in order to facilitate the acquisition of tectonic information by users, who do not specialize in remote sensing. The studied area covers a great part of NW Greece (Epirus Prefecture). During the summer and autumn of 1996, this region was affected by strong and disastrous earthquakes (up to 5.6 R). Data from Landsat TM have been selected and processed creating a false colour composite image and then analyzed and interpreted in order to detect the tectonic features.
