• Giorgio dal Piaz → Edoardo Semenza (Conflict Competing Geological Assessments) — Their assessments stood in opposition: Dal Piaz's assessment was trusted, while Edoardo's warning was dismissed.

Story Analysis

Warnings about the danger of the Vajont dam are dismissed before a landslide and flood devastate the towns below.

Plot Progression

1. A Dam Above Mount Toc — Engineer Semenza plans the Vajont dam to carry electricity across the country. The artificial lake and the towns below establish the setting for the danger that follows.
2. Merlin's Persistent Warnings — Tina Merlin repeatedly denounces the danger of building near Mount Toc. She also tries to expose omissions by politicians and workers in charge of construction.
3. Conflicting Geological Assessments — Edoardo Semenza's analysis warns of geological danger. Those in charge instead trust Giorgio dal Piaz's assessment, and the warnings are dismissed.
4. The Fatal Night — The danger remains unrecognized until October 9, 1963. At 10:39 pm, a massive landslide falls from Mount Toc into the artificial lake.
5. The Flood's Aftermath — The landslide generates a huge wave, and water destroys the towns below the dam. The reference reports that more than 2,000 people are killed.
