Predicting volcanic eruptions is never easy. centuries, volcanologists and seismologists have studied the activity Earth that might indicate an eruption. Forecasting when a volcano might erupt has been somewhat unreliable. However, scientists NASA and the Smithsonian Institution say they are a step closer to providing more accurate forecasts of when a volcano might blow. NASA used images space to detect changes the colour leaves. The research was based a 2019 study from McGill University. This study showed that an increase carbon dioxide levels emitted by two active volcanoes Costa Rica had an impact on the colour of leaves the surrounding areas.
Current methods predicting an imminent volcanic explosion include checking seismic activity, changes ground height, and carbon dioxide and sulphur dioxide emissions. NASA said the new method monitoring changes the colour of foliage space could help in foretelling eruptions. The science behind this is fairly straightforward. As magma moves upwards Earth's crust, it releases carbon dioxide. Trees absorb this and their leaves become greener and more vibrant. The LiveScience website said: "These signs can help to protect communities the worst effects volcanic blasts, including lava flows, ejected rocks, ashfalls, mudslides, and toxic gas clouds."
