Volcanoes Send Secret Signals Through Trees And NASA Satellites Can See Them

Trees near volcanoes might be the early warning signs scientists have been looking for — and now, they can be watched from space. A NASA-Smithsonian collaboration has revealed that carbon dioxide released from rising magma makes surrounding vegetation greener, a subtle but trackable signal. Using satellite imagery and ground validation, researchers are crafting a powerful [...]

Scientists Discover How Trees Secretly Signal Deadly Volcanic Eruptions from Space

Scientists have uncovered a promising new way to detect volcanic unrest by monitoring changes in vegetation near volcanoes, observable from space. Research highlighted in a recent article on SciTechDaily, together with findings shared by the Smithsonian Tropical Research Institute’s Airborne Validation Unified Experiment: Land to Ocean (AVUELO) mission, shows how trees absorb volcanic carbon dioxide emissions, resulting in greener foliage. This …

Their understanding will change a lot.
