Guatemala authorities say lava flowing from the Pacaya volcano near Guatemala City is prompting the evacuation of those living nearest the crater.
Back when he was working on his Ph.D. in geophysics at the University of Chicago in the 1980s, Dork Sahagian took a break one day from studying lava flows to attend a lecture on how raindrops form in clouds.
An unconventional research method allows for a new look at geologic features on Earth, revealing that some of the things we see on Mars and other planets may not be what they seem.
A growing lava stream threatening homes on Hawaii's Big Island is expanding as it heads toward a small rural town.
The eruption of the Fuego volcano in Guatemala was likely a "pyroclastic surge" similar to the one that destroyed the ancient city of Pompeii, says volcanologist David Rothery of The Open University in England.
Jeffrey Karson, a Syracuse University geologist who recently traveled to Iceland to monitor the early stages of the eruption, says the lava field now covers more than 22 square miles (or 14,000 acres), nearly the size of ...
Dozens of earthquakes were rattling Hawaii's Kilauea Volcano on Wednesday as underground magma moved into a new area east of the Puu Oo (POO'-oo OH'-oh) vent.
Primeval lava flows formed the massive canyons and gorge systems on Mars. Water, by contrast, was far too scarce on the red planet to have cut these gigantic valleys into the landscape. This is the conclusion of several years ...
(PhysOrg.com) -- Latest research into the age of volcanos in Western Victoria and South Australia has confirmed that the regions are overdue for an eruption, potentially affecting thousands of local residents.
As volcanologists at Lamont-Doherty Earth Observatory, we love everything lava. Right now, we're exploring how the structure of the surfaces lava flows over influences how it advances. Does it matter if the lava is flowing ...
