A volcano is an opening, or rupture, in a planet's surface or crust, which allows hot magma, volcanic ash and gases to escape from the magma chamber below the surface.
In a groundbreaking study, researchers at University of Miami (UM) Rosenstiel School of Marine & Atmospheric Science used satellite imagery to study volcanic eruptions from the past years in Indonesia’s west Sunda arc, a highly active volcanic region. Their findings show that images of inflating magma balloons hint towards impending volcanic eruptions in one in two cases, on [...]
Analysis of crystal formed in the molten rocks of a volcano might predict volcanic eruptions with as much as a year in advance, researchers claim. Mixing Seismology and Petrology Drawing data from the volcanic activity of Mount Helens from 1980 through 1986, geologists found that iron- and magnesium-rich crystals grow before an eruption, and by [...]
For the past few months, the mighty Katla volcano, close to the Icelandic coast, has been exhibiting intense seismic activity, hinting towards an imminent eruption. With a caldera of 10 kilometers, a long history of causing havoc and pain, Katla has the potential of flooding the Atlantic Ocean with billions of gallons of water left [...]
Spectacular range smoke, ash and lava shot up in to the night sky last night from Africa’s most active volcano, located in the Democratic Republic of Congo’s Virunga National Park. Congo’s Centre for Research and Natural Sciences claimed in a recent statement that local residents, as well as the precious endangered mountain gorillas living in the park, are not [...]
A dramatic overnight increase in seismic activity near the Katla volcano in southern Iceland has brought fears of a dramatic eruption, one that would make last year’s massive air-traffic disruption seem like a walk in the park. “It is definitely showing signs of restlessness,” commented Pall Einarsson, a professor of geophysics at the University of [...]
