When you picture a volcano ... is that we know much less about magma chambers like this than we’d like to. We’re not even good at depicting them. “We draw them as red balloons,” says ...

Geologists turned to tiny bubbles to investigate the dynamics driving magma flow beneath Hawaii’s volcanoes as the country’s islands drift northwest on a tectonic plate. They found that, as the ...

Seismic imaging and computer models were used to determine the depth and structure of the magma system. For many years, it has been known that one of the largest active volcanic systems in the ...

The new findings suggest that the Yellowstone magma reservoir is "actively releasing gas while remaining in a stable state," said the press statement. The stability of the volcanic system is ...

In fact, that depth tells geologists information about the volcano’s future threats. “We know what pressures are going to be and how bubbles are going to come out of the magma,” Farrell said in the ...

At volcanoes like Kilauea, the bubbles are primarily CO2. The density of CO2 in a fluid inclusion is sensitive to the pressure the magma was under ... and be used to draw analogues with past ...

With the ash column obscuring the volcano, and much of the volcano submerged underwater, scientists will need time to gather more indirect data before drawing any conclusions. Clues could come ...

Long-quiet volcanoes in the Cascades region of the Pacific Northwest are still underpinned by large reservoirs of magma, new research finds. The findings have implications for monitoring volcanoes ...

However, a team of scientists recently found magma chambers lurking beneath six volcanoes in the Cascade Range. The findings published January 23 in the journal Nature Geoscience are challenging ...

Magma composition may drive volcanic tremor Daily ashfall sampling at Cumbre Vieja volcano in the Canary Islands demonstrates potential for near-real-time eruption monitoring and forecasting tool ...

A mysterious type of magma found within extinct volcanoes scattered around the world could contain an abundant supply of rare earth elements, crucial ingredients for electric vehicles, wind ...
