NASA has revealed a groundbreaking method to detect early volcanic activity—by watching trees from space. As magma rises, it releases CO2, which trees absorb, turning greener. This subtle change is now detectable through satellite imagery.
By combining satellite data with seismic activity and ground swelling, volcanologists can better predict eruptions and issue timely evacuation warnings. This technique could revolutionize how we monitor the 1,500+ active volcanoes around the world.
Traditionally, tracking volcanic gases requires dangerous fieldwork. Earth Observation (EO) offers a safer, broader alternative. NASA and the Smithsonian’s research highlights how EO can protect the 10% of the global population living in volcano hazard zones.
Beyond volcanoes, EO is a key asset in climate monitoring and environmental management. A recent Forum white paper outlines how EO innovations can enhance global climate action and intelligence.
