Although volcanic eruptions may seem like a distant worry for many of us, about 10 percent of the world’s population lives within striking distance of a volcano. This includes those living in the U.S., which is, according to the U.S. Geological Survey, one of the world’s most volcanically active countries.
The widespread threat is why many scientists are working to discover early warning signs of volcanic activity. A new study, published by NASA, revealed an unlikely hero stepping up to help warn of impending eruptions – trees.
In a collaboration between NASA and the Smithsonian Institution, researchers have found that changes in tree leaves in the area surrounding a volcano can indicate when the volcano might erupt. By using NASA satellite images to monitor these trees, evacuation warnings can be sent out earlier than ever.
“Volcano early warning systems exist. The aim here is to make them better and make ...
