Abstract

The May 28, 1990, eruption of Nevado Sabancaya volcano ended a dormant stage of about 200 years duration. This ice-clad stratovolcano still poses a threat to about 35 000 people and to irrigated land in the Rio Colca and Siguas valleys. This study develops a model for volcanic hazard appraisal and hazard-zone mapping available for remote stratovolcanoes like Nevado Sabancaya which lack geological information. The method is based on remote sensing using 5 SPOT images collected during 1990, geological and geomorphological survey of the summit volcano, and calculation of parameters for tephra dispersal and pyroclastic flow. -from English summary
