Trees Warn of Volcano Eruptions—Satellites Are Watching
Imagine trees screaming a warning before a volcano erupts—now satellites can hear them
Imagine nature’s own alarm system: trees near volcanoes turn unusually lush and green as magma rises underground, releasing CO₂ that supercharges their photosynthesis. Using NASA’s Landsat and ESA’s Sentinel satellites, scientists track these ‘greening patterns’ with a tool called NDVI—sometimes spotting changes weeks before an eruption!
This groundbreaking discovery was made around Mount Etna in Italy and volcanoes in Costa Rica, where vegetation visibly transformed before disaster struck.
‘This could be a game-changer for early warning systems,’ said a researcher from the team studying volcanic vegetation patterns.
Experts are buzzing—one volcanologist called it ‘a stunning blend of nature and tech,’ amazed at how trees could help predict deadly eruptions.
Could this save countless lives in the future? Imagine communities getting a heads-up from the trees around them—nature and science teaming up like never before. What do you think this means for disaster prevention?
