Latest Magma Stories
From Pompeii to Mount St. Helens, we humans have watched in awe, and sometimes horror, the magnificence of volcanic eruptions.
Scientists have identified a trigger for the largest explosive volcanic eruptions on Earth, according to a report published in the journal Scientific Reports.
How often have you wished you could safely see a lava flow, like the one that destroyed Pompeii? Did you ever wish you could see it in Syracuse, New York?
New research from a group of scientists led by Denis Andrault from the Laboratoire Magmas et Volcans of University Blaise Pascal provides experimental evidence for the mantle plume hypothesis.
Orange-like rocks in Utah with iron-oxide rinds and fossilized bacteria inside that are believed to have eaten the interior rock material, plus noted similarities to "bacterial meal" ingredients and rock types on Mars; fine-tuning the prediction of volcanic hazards and warning systems for both high population zones and at Tristan da Cunha, home to the most remote population on Earth; news from SAFOD; and discovery in Germany of the world's oldest known mosses.
Volcanoes capable of super-eruptions that could be catastrophic for civilizations have short fuses, according to new research conducted at Vanderbilt University.
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.
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....
