Authors(s) and Affiliation(s)



A method is presented to monitor the development of geomorphic hazard areas by overlaying time series of air photos in a digital image processing system. This study deals with such hazards affecting an urban area, Villavicencio at the foot of the eastern Andes in Colombia. In this particular case, the hazards principally affect the city's links with the outside world : the only highway to the centre of Colombia is threatened by a major landslip; the civil airport, by flooding
