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 at Washington State University and the University of Idaho have discovered a new way to estimate how fast magma is recharging underneath the Yellowstone supervolcano. Unfortunately, their ...

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 ...

It’s not hard to see why researchers are worried about a Yellowstone eruption. If the supervolcano were to erupt, the ...

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 ...

Submitted by Lockwood DeWitt: How does bimodal volcanism work? Bimodal volcanism is whenever you have a volcano that erupts basalt and rhyolite ... and really nothing else in-between. What does that ...

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 ...

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 ...
