Scientists have finally unraveled the mystery behind the powerful volcanic eruptions that catapult diamonds from deep within the Earth, scattering these precious gemstones across the planet's surface.
GPS equipment can track very subtle ground movements.
It was huge, and we might have missed it completely!
New England residents shouldn't panic, though. There won't be a volcanic eruption in their backyard anytime too soon.
The Permian extinction was the biggest extinction ever, killing 96% of all marine species and 70% of terrestrial vertebrates Possible causes include: impact, loss of oxygen and volcanic eruptions Researchers tested the validity of the last hypothesis, finding it likely The biggest extinction – ever MIT Researchers believe that rain as acidic as undiluted lemon […]
Even an area so studied as Hawaii sometimes yields surprises – a recent study conducted by researchers at the University of Hawaiʻi at Mānoa School of Ocean and Earth Science and Technology (SOEST) and the University of Rhode Island (URI) changes the very foundation of how the Hawaii islands were formed: it is the eruptions […]
What do volcanic eruptions, oil spills, sewages and chimneys all have in common? Not much at a first glance – but if you ask Peter Baines, a scientist at the University of Melbourne in Australia, they are tightly connected; in all these events, a fluid rises into a environment stratified by density (like the atmosphere […]
Lots of volcanoes erupted in 2009 – but one of them really screamed out. Its unique howls provide a glimpse into the very heart of the volcano, and also in some unexplained processes that accompany an eruption. It’s not unusual for swarms of small earthquakes to precede a volcanic eruption – it’s quite common. As […]
The Pavlof volcano lies in the long chain of the Aleutian Islands off the west coast of Alaska, and is one of the most active volcanoes in the United States. It’s about seven kilometers (4 miles) across and 2500 meters (1.5 miles) high; after being quiet since 2007, it started erupting again in May 2013. […]
Usually, the military taps into what science does and uses its technologies – but for once, it was the other way around. Using unmannes planes typically designed for city warfare, scientists were able to keep track of toxic volcanic fumes. The Dragon Eye remote-controlled plane weighs in at just under 6 pounds (2.7 kilograms), with […]
Details of some 2000 volcanic eruptions that occurred in the past 1.8 million years are now available in a new open access database, complied by scientists at the University of Bristol with help from the UK, US, Colombia and Japan. Volcanic eruptions are among the most dangerous natural hazards, having the potential to take numerous […]
For his fantastic Lord of the Rings trilogy, director Peter Jackson relied on two volcanoes in New Zealand, Mount Ngauruhoe and Mount Ruapehu, to portray Mount Doom. The latter, however, is keen on showing that it can be bad off-screen as well, after geologists warn that it’s nearing an impending eruption. “The current situation can’t […]
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 […]
Sakurajima is probably the most active and dangerous volcano in Japan. Actually, one of its eruptions from back in 1914 is still attested as the the most powerful volcanic eruption in Japanese history, which at the time engulfed a whole city in ash and lava, and joined the former island with the neighboring Osumi Peninsula. […]
Volcanic eruptions are impressive natural phenomena; it begins when pressure on a magma chamber forces magma up through the conduit and out the volcano’s vents. Seen on the TV or in the newspaper, they’re just fantastic and gorgeous. But if you’re unlucky enough to be there… it’s really deadly. But volcanic ash can also bring […]
