Why Do Scientists Use Heat Cameras on Volcanoes?
Scientists use heat cameras on volcanoes because a thermal camera sees heat, not light. It can show hot spots, warm cracks, and glowing lava, even through smoke or in the dark. A warming crater can be an early clue.
More fun facts
- Thermal cameras make images using colors that show temperature.
- Scientists use them to keep watch on hot lava.
- A thermal webcam on the rim of Halemaumau crater watched Kilauea's lava lake.
- Hot spots at the surface can reflect heat changes underground.
- Scientists also use satellite images to look for unusual heat at volcanoes.
