In the early 20th century, sailors near Alaska reported seeing black bubbles seeming to boil out from the sea, each one the size of the dome of the capitol building in Washington, D.C. They weren't ...

The explosiveness of a volcanic eruption depends on how many gas bubbles form in the magma—and when. Until now, it was thought that gas bubbles were formed primarily when the ambient pressure dropped ...

Scientists are still discovering new aspects of eruption of an underwater volcano near Tonga last year that sent plumes of ash 35 miles above the ground. The latest finding of this powerful eruption ...

A new study on the connection between earthquakes and volcanoes took its inspiration from old engineering basics. Future applications of these results may enable better predictions of the likelihood ...

When the eruption of an underwater volcano near Tonga crescendoed into a fiery blast last year, it sent shock waves around the globe. Its eruption was stronger than an atomic bomb and set new records ...

As magma squeezes its way out of a volcano, bubbles of lava-coated hot gas form. Volcanologists now report these emissions tell a more complex story of the chemistry going on during volcanic eruptions ...

A rare event was caught on camera over the weekend at Italy's Mount Etna, the most active stratovolcano in the world. The Sicilian volcano was seen spewing rare and nearly perfectly circular volcanic ...

In late 2017, a remote stretch of water in the Bering Sea turned into a bubbling cauldron. A remote volcano, called Bogoslof, whose vent sits roughly 350 feet below the surface, came to life. The ...

Why are volcanologists interested in vapor bubbles? Because they can accumulate in a magma reservoir underneath a volcano, priming it to explode. Researchers have now discovered how bubbles are able ...

Satellite imagery of the Bogoslof Volcano, in the Aleutian island chain in Alaska. The stories seemed just tall tales of the sea, told by experienced marines to frighten fresh naval recruits. Sailors ...

In 1784, Benjamin Franklin made what may have been the first connection between volcanoes and global climate while stationed in Paris as the first diplomatic representative of the United States of ...
