Balancing risk and heritage: Geospatial assessment of tourism vulnerability in volcanic landscapes of Arequipa, Perú

This study explores the relationship between geodynamic hazards and community-based tourism in the Sillar Quarries of Aashuayco, Arequipa, Peru.Through GIS-based mapping, we assessed volcanic activity, fluvial events, and mass movements affecting the tourism infrastructure.Data from INGEMMET, field mapping, and tourism records revealed that while volcanic ashfall poses a moderate threat, sudden rockfalls from intensive quarrying are the most immediate risk.Despite receiving over 350 tourists daily, the area lacks formal contingency plans or structural safety measures.Comparative cases from Indonesia and New Zealand stress the urgency of geotechnical assessments, signage, and evacuation routes.The study highlights the importance of integrated risk governance to ensure safety while preserving geological heritage and supporting sustainable community tourism.
