Based on Landsat TM images, the glaciated surface of Cordillera Blanca (Peru) has been estimated at 643 km 2 for 1987 and at 600 km2 for 1996. The development of three potentially dangerous glacial lakes in the Northern part of this area was surveyed using these images, together with additional ones for 1975 (MSS) and 2000 (ETM+).Text/Conference Paper
