Oct. 22 (UPI) --Most volcanic eruptions are of the basaltic variety. The eruptions are typically rather tame. Every once in a while, however, the same types of eruptions turn violent and explosive.

Volcanic activity bubbling away beneath the Yellowstone National Park in the US appears to be on the move. New research shows that the reservoirs of magma that fuel the supervolcano's wild outbursts ...

Researchers have found a new way to estimate how fast magma is recharging beneath the Yellowstone supervolcano. While their findings offer no help in predicting if the volcano will erupt, they can now ...

The NASA Earth Observatory has been doing an excellent job ofmonitoring the eruption at Eritrea's Nabro using all their eyes in the sky. The latest image, taken from the EO-1 Advanced Land Imager (see ...

Far beneath the Earth's surface, a fiery world of viscous molten rock exists below the continental and oceanic plates, perpetually churning and shifting under the immense pressure and stress of a ...

Researchers have discovered that some seemingly "monotonous" volcanoes with reliable patterns of low-level activity may be hiding a secret deep below the surface—magma which has the potential to erupt ...

The origin and stability of deep-mantle melts, and the magmatic processes at different times of Earth’s history are controlled by the physical properties of constituent silicate liquids. Here we ...

This news release is available in German. Using the world's most brilliant X-ray source, scientists have for the first time peered into molten magma at conditions of the deep Earth mantle. The ...

A new variation diagram has been devised in which the ratio $\frac{Total O not combined in OH^{-}}{Si^{+4}+ (A1^{+3} in 4-co-ordination)}X10$ is plotted as abscissa. This ratio, here called the ...
