| Résumé : | Volcano-related lakes represent some of the most diverse physical and chemical settings on Earth. Despite a broad range of water chemical compositions, they are all connected directly or indirectly to the release of high-temperature gases from magmatic intrusions within their parent volcanic system and are commonly found in craters formed by hydrothermal or volcanic eruptions. Such lakes can be associated with a range of hazards, including base surge, debris flow, flank collapse, and toxic gas release. Some volcano-related lakes host long-lived molten sulfur bodies, and acid crater lakes were probably present at the summit of volcanoes that hosted ore formation. Various techniques are deployed to monitor the activity of volcano-hosted lakes, and examples exist of successful efforts to reduce their associated hazards. |
