Scientists Just Discovered Trees Near Volcanoes Warn Us Before They Erupt — And Satellites Can Detect the Signals from Space

Trees could thrive near volcanoes because of several factors, including their ability to release massive amounts of carbon dioxide, which could enhance photosynthesis. This is also the same mechanism that scientists have recently discovered could be used to detect if a volcano is about to erupt.

Forests as Natural Sensors

As magma rises from deep within the volcano, it will release Carbon Dioxide that the surrounding trees in the area absorb. This event will trigger an increase in photosynthesis, making trees greener.

This physiological response creates a detectable warning signal long before any visible or seismic eruption signs appear. Satellites like Landsat 8, Sentinel‑2, and NASA’s Terra can monitor these changes from Space. In simpler words, scientists have just discovered that trees have a way to warn us before a volcanic eruption occurs.

Scientists Discover Trees Predict Volcanic Eruptions

Researchers from NASA, the Smithsonian Institution, the University of Houston, and McGill University launched the AVUELO campaign, which aims to verify and calibrate the CO₂ sensors and airborne spectrometers to confirm that the satellites are monitoring the greenness of the trees correctly.

After confirming that trees could reliably be observed to turn greener and increase their photosynthetic activities before eruption, NASA and other space organizations now aim to maintain this monitoring system to alert the population if any major eruption is about to happen based on the trees’ photosynthetic activities.

Why It’s a Game-Changer

Traditional monitoring systems for when volcanoes are about to erupt are costly and sometimes inaccurate. This technology includes seismic sensors, gas detectors, and ground deformation, but it is very limited in remote regions.

This is because mountainous areas often lack the infrastructure needed for reliable energy and communication, which is vital for the monitoring system to transfer data quickly; otherwise, it would not be able to alert anyone.

However, trees are different; they are inexpensive, and the NASA satellites required are already orbiting Earth, executing multiple missions. Which means, nature warning us, is a more passive, low-cost, and wide-range proxy that could tell us in advance if a volcano is about to erupt. We just need to listen.

Limits and Next Steps

This vegetation-based system is very effective and precise, but its limitation is hard to overcome. If this method relies on trees’ photosynthetic activities to detect possible volcanic eruption, then what happens if the volcano lies in a barren terrain that lacks trees?

It takes time and more resources to create a forest around a volcano for the sole purpose of detecting when it could erupt. Other external factors, such as wildfires and diseases, also make this challenge not worth it, as a better and safer option exists.

However, with all of that said, for volcanic areas with vast vegetation, this new discovery and method for the detection of possible eruptions is one of the best. It’s like nature itself is helping to warn us about the incoming danger.

Author's Final Thoughts

Trees near volcanoes silently respond to gas long before an eruption becomes obvious. Combining it with our own technology and intel from satellites, we would be able to create the most powerful and effective nature-based system for detecting warnings that may one day very well save countless lives.
