“…El Misti volcano and the threat that it poses to Arequipa has been the focus of a second major volcanic research initiative, conducted by a team of French, German and Peruvian scientists from a number of institutions. It has focused on questions of both pure research and hazard assessment, and is based on techniques of ground‐based geological and hazard mapping, remote sensing (especially using SPOT satellite images), chronological studies using radiometric dating procedures and the interpretation of historical source materials (Chorowicz et al 1992; Thouret et al 1995 1999a 1999b 2001 2003; Juvigné et al 1998; Anon 1999a; Lara et al 2000). It concludes that even a moderate eruption of the volcano, such as that which occurred between AD 1440 and 1470 with an estimated recurrence interval of 500–1500 years, would cause considerable problems for the densely populated areas in and around Arequipa.…”

Over the last 15 years there have been dramatic shifts in the consensus over how best to cope with natural hazards in economically developing regions such as South America. One very positive outcome of the United Nations sponsored International Decade for Natural Disaster Reduction (IDNDR 1990–2000) has been that there is now greater interchange between the work of earth scientists examining the processes and mechanics of hazard occurrence and impact, and social scientists exploring the causes of human vulnerability to hazard – and thereby disaster. This paper traces the development of this new understanding with reference to earthquakes and volcanic eruptions in Peru, one of the most hazardous countries in South America. Particular focus is placed on the excellent progress currently being made by scientists in better understanding the physical dimensions of natural hazard exposure, and the ground‐breaking work by social scientists in promoting new approaches to understanding and mitigating human vulnerability to disaster. The paper concludes by emphasizing the need to build on this research to produce more inclusive, incultured and unified strategies of disaster mitigation at the local, national and international levels.

SPOT XS and Panchromatic images are used jointly in order to map the lava¯ows of the Nevado Sabancaya volcano (southern Peru). This mapping is achieved through two types of processing: the unsupervised multispectral clustering applied to the XS image, and some speci® c methods of image analysis (mathematical morphology, convolution ® ltering ) applied to the Panchromatic image.The resulting images allowed us to identify¯ows and the two main morphological features of the¯ow areas: lava reliefs and¯ow lines. Therefore, our experience shows that image analysis can be a tool for thematic mapping which displays more capabilities than photointerpretation.
