Trees Can Provide Early Warning of Volcanic Eruptions, NASA Finds

Scientists are exploring a new method for predicting volcanic eruptions by analyzing satellite images. Observing changes in vegetation could reveal underground carbon dioxide emissions, offering a valuable tool for early warning in remote areas. Active volcanoes, like the one pictured, emit gases that can predict an eruption. Today, thanks to satellites, nearby vegetation can reveal these invisible changes. Volcanic eruptions are phenomena as im…

Trees can provide early warning of volcanic eruptions, NASA finds

Volcanoes often give little warning before they erupt, but now scientists have discovered an unexpected early warning sign—trees. This new finding comes from a joint study by researchers from NASA, the Smithsonian Institution, and various universities who have shown that changes in tree leaves can indicate rising volcanic activity. More importantly, satellites can spot these changes, potentially providing a safe, cost-effective way to predict vo…
