In a fascinating twist of nature-meets-tech, scientists have discovered that trees near volcanoes change their behavior before an eruption. 

How? As magma rises underground, it releases carbon dioxide (CO₂) — and surrounding trees absorb this extra gas, becoming noticeably greener.

🌿 These subtle changes in vegetation health are invisible to the naked eye…

📡 But satellites like Sentinel-2 and Landsat can detect them using tools like the Normalized Difference Vegetation Index (NDVI).

🔬 Studies around Mount Etna showed that greener vegetation often correlates with magma movement, providing an early warning sign days or even weeks before an eruption!

🌎 The AVUELO mission also tested this tech in Costa Rica and Panama, proving how remote sensing + ecological signals = smarter, safer volcano monitoring.

🚨 This method doesn’t replace traditional warning systems like seismic sensors, but it offers a powerful new layer of insight, especially in remote or poorly monitored areas.

💡 Nature speaks — and now we can finally listen from space!
