Abstract

Panagopoula landslide is one of the most famous disasters occurred in Greece during the last fifty years. Many studies describing the geology of the broader area and the geotechnical characteristics of the landslide that took place on May 1971 have been published. The specific instability zone has been activated in the past several times and remains active until now. According to the literature, the landslide was 350m wide and the landslide materials had covered and destroyed totally the highway and the railway. For many months, the land transportation between Athens and Patras was interrupted and ferries carried all the vehicles between two piers that were constructed in the broader area. In 1972, another big mass movement was activated on the same place. Although, Panagopoula landslide is very well studied an accurate mapping of the slide area and calculation of the mass volume has never been performed. In the current study aerial photos and Declassified Satellite Imagery were processed in order to map the landslides extent fifty years after the disaster. Digital Photogrammetry and GIS techniques were combined and the results are presented.
