Sustainable Management of Landslides in Ecuador: Leveraging Geophysical Surveys for Effective Risk Reduction

The present work explores the use of geophysical surveys as valuable tools for the study and sustainable management of landslides, with a particular focus on Ecuador. As an Andean country, Ecuador’s geomorphology and geology are dominated by volcano-sedimentary materials and processes, which confers...
