Why are “giant fountains of lava” suddenly pouring out of some of the most dangerous volcanoes on the entire planet, and why are so many long dormant volcanoes suddenly roaring back to life?
The spectacular eruption of Mt. Etna in Italy is making headlines all over the world, but it is far from alone.
According to Volcano Discovery, 35 major volcanoes either are erupting right now or have just recently erupted, and dozens of others are stirring.
So what is causing this upsurge in volcanic activity? Is something strange happening inside the Earth?
According to the USGS, magma is “molten rock underground”, and lava is molten rock “that breaks through the Earth’s surface”.
