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 ...

A massive underwater volcano off the Oregon coast, known as the Axial Seamount, may erupt as soon as tomorrow, scientists warn. The seafloor has swelled to levels seen before its last major eruption ...

Underneath Yellowstone National Park, magma bubbles and flows. But exactly how close it is to the surface has long been a mystery to scientists — until now. For the first time, researchers have ...

Geoscientists discovered a magma cap acting as a "lid" 2.4 miles beneath Yellowstone. This magma cap traps heat and pressure, but also allows gas to vent, reducing eruption risk. Seismic imaging ...

Brandon Schmandt, a professor of earth, environmental, and planetary science at Rice University, told Nexstar that scientists have long known that there is magma beneath Yellowstone. But being ...

Fortunately, clues at the surface, such as earthquakes and ground deformation, can indicate movement within underground magma dikes—sheets of magma that cut across layers of rock. Scientists can ...
