Scientists may have discovered a new potential trigger for volcanic eruptions. They've found that a pressure drop associated with a structure known as a sill may actually trigger a volcanic eruption.
Io is the innermost of the four moons of Jupiter and is also the most geologically active body in our solar system. Now, scientists have taken a closer look at the largest of its volcanic features, named Loki, on its surface.
Scientists have produced a new map of the moon's most unusual volcano, revealing that its explosive eruption spread debris over an area much greater than previously thought.
Some geysers, like Old Faithful in Yellowstone National Park, erupt on a timer, keeping to a regular schedule. Now, scientists may have found out why. It turns out that these geysers have loops or side-chambers in their underground plumbing.
It turns out that seafloor volcanoes may cause climate change. Scientists have taken a closer look at the way seafloor volcanoes flare up from time to time and have found that the pulses may actually help trigger natural climate swings.
Where do volcanoes come from? Researchers have announced that a layer beneath Earth's crust may be responsible for volcanic eruptions.
Could volcanoes be slowing global warming? That may just be the case. Scientists have found that small volcanic eruptions could be slowing the warming process across our planet.
Scientists have found that the reservoirs of supervolcanos consist of magma that intrudes into the crust in the form of numerous horizontally oriented sheets resting on top of each other like a pile of pancakes.
Plumes from Earth's mantle may just break up entire continents. Scientists have taken a closer look at the material rising up from the boundary layer of Earth's core and have found that they can help shape our planet's surface.
How explosive would a volcanic supereruption at Yellowstone National Park be? It would be pretty devastating.
Three massive volcanic eruptions on Jupiter's moon, Io, have made astronomers think twice about how often these outbursts occur.
Scientists are getting a closer look at Mount Rainier's volcanic plumbing. By measuring how fast Earth conducts electricity and seismic waves, researchers have made a detailed picture of what happens deep beneath the surface of the mountain.
