Latest Magma Stories
By studying crystals formed in volcanic rock, experts may be able to predict an impending eruption up to a year in advance, researchers from the University of Bristol have discovered.
Oxygen-based life evolved on Earth because of geological events that occurred over 2.5 million years ago, according to Princeton University researchers who published a report this week in the online journal Nature.
Two new studies into the "plumbing systems" that lie under volcanoes could bring scientists closer to understanding plate ruptures and predicting eruptions—both of which are important steps for protecting the public from earthquake and volcanic hazards.
Two new studies into the "plumbing systems" that lie under volcanoes could bring scientists closer to predicting large eruptions.
GEOLOGY posted ahead of print 14 Feb.–2 Mar. is a dynamic collection of papers covering modeling studies of the U.S. New Madrid Seismic Zone; landslide prediction through examination of the Slumgullion landslide, Colorado; investigation of a potential nuclear waste repository site in Finland; understanding river delta formation and long-term evolution with insights from the Mekong River, Vietnam; and an explanation of how drought drove forest decline and dune building in eastern upper...
A team of Dutch scientists believe that they have discovered why there are no active volcanoes on the Moon, even though recent seismic activity suggests that there is a good amount of magma below the surface.
Like a stream of air shooting out of an airplane's broken window to relieve cabin pressure, scientists at Scripps Institution of Oceanography at UC San Diego say lava formations in eastern Oregon are the result of an outpouring of magma forced out of a breach in a massive slab of Earth.
Phase transitions in liquid magmas at the pressure and temperature levels that exist deep within Earth-like planets could play a role in the formation of new worlds.
New research suggests that eruptions at some of Earth's largest volcanoes could be predicted decades before the event actually occurs, potentially making it easier for experts to monitor danger zones and conduct pre-emptive evacuations to keep residents out of harm's way.
Scoria is a term used by geologists to describe an igneous rock containing many gas bubbles, or vesicules. Scoria forms when magma rich in dissolved gases is vented. As the magma encounters lower pressures, the gasses are able to escape and form bubbles. These bubbles are trapped when the magma cools and solidifies. Volcanic cones of scoria can be left behind after eruptions, usually forming mountains with a crater at the summit. An example is Mount Wellington, Auckland in New Zealand....
