Meteorologist Craig Moeller talks about the New Jersey wildfires, Yellowstone's magma cap, and space journey preparations.

For the first time, geoscientists detected the top of Yellowstone’s magma reservoir. It is active and dynamic, but not in danger of erupting, they found.

When magma becomes too much to handle, gases will not be able to exit the landform. This leads pressure to build up and will eventually cause an explosion of gas and lava, according to the USGS.

Scientists have worked out the consistency of the magma under the Yellowstone caldera using seismic waves — and the reservoir is filled with "mush" that doesn't pose an imminent eruption threat.

Oregon’s Three Sisters volcano complex is showing signs of increased activity as magma moves beneath the surface, raising concerns about potential volcanic eruptions. This video provides the ...

Though immensely powerful, volcanoes are not always spewing hot lava around. Many are considered dormant or even extinct and have not shown their strength for hundreds of thousands of years in ...

Once the rock melted and became “magmatic,” the iron-rich magma absorbed all the rare earth elements from its surrounding environment, according to the study, which concluded this iron-rich ...
