Scientists have developed a new algorithm for early warning systems for volcanic eruptions.
According to UCLA volcanologist and Dr. Teresa Ubide, scientists previously believed that the cooled lava from volcanoes in hotspots was previously magma that was in the mantle below the Earth’s surface. But that’s not entirely true, the doctor adds.
The structure of volcanoes is more complicated than scientists imagined. Volcanoes filter their contents and, as a result, a completely different substance appears on the surface.
Due to the complex system of the volcano, the minerals in the magma crystallize. Rising magma recycles these minerals and changes their overall chemistry.
The authors found that volcanoes in hot spots filter their melts at the base of the crust, in which case a powerful eruption occurs.
If you closely monitor the volcanoes and monitor whether the magma reaches the base of the earth’s crust, then you can predict an eruption. The results of the work confirm that if magma is located on the border of the crust and mantle, then an eruption should occur in the near future.
