How is Kilauea monitored?
The volcano’s daily activities (for example, lava flow movement, earthquakes, surface deformation, and gas production) are monitored by U.S. Geological Survey personnel at the Hawaiian Volcano Observatory (HVO ). Kilauea has been monitored ever since, making it one of the best-studied volcanoes.
How are Hawaiian volcanoes monitored?
The primary methods for monitoring active lava flows include ground and aerial observations and mapping, webcam imagery, satellite data and images, and collection of lava samples for temperature, chemical, and mineral analysis.
