Part 6/16:
Environmental and social impacts worsened as construction disturbed ecosystems and damaged local communities. Underground excavations destroyed aquifers used by villages, causing walls and ceilings to collapse and forcing families into temporary shelters. Flooding problems worsened as earth dumped into rivers reduced their capacity to drain water efficiently, exacerbating flash floods. Hillside destabilizations triggered landslides, threatening nearby towns already vulnerable due to volcanic soils.
