Abstract
Where abrupt and dangerous natural phenomena unfold in highly populated areas, they destroy buildings and infrastructure and, above all, cause death and injury among local inhabitants. In the case of the active Ecuadorean volcano Cotopaxi, eruptions have already posed considerable threats to nearby towns and cities due to activated mudslides (lahars) that flow rapidly down its slopes. Interviews conducted with inhabitants of vulnerable residential areas of the town of Latacunga have led the authors to conclude that – in danger zones associated with possible mudslides – the lack of building land, inappropriate management of the allocation of building plots and still-inadequate early warning and monitoring systems have favoured the chaotic spread of built-up areas and thus pose a threat to the lives of inhabitants should Cotopaxi erupt again.
