Analysis of crystal formed in the molten rocks of a volcano might predict volcanic eruptions with as much as a year in advance, researchers claim. Mixing Seismology and Petrology Drawing data from the volcanic activity of Mount Helens from 1980 through 1986, geologists found that iron- and magnesium-rich crystals grow before an eruption, and by [...]

Volcanic eruptions are impressive natural phenomena; it begins when pressure on a magma chamber forces magma up through the conduit and out the volcano’s vents. Seen on the TV or in the newspaper, they’re just fantastic and gorgeous. But if you’re unlucky enough to be there… it’s really deadly. But volcanic ash can also bring [...]
