  • Is Something Strange Happening Inside the Earth?

    Why are “giant fountains of lava” suddenly pouring out of some of the most dangerous volcanoes on the entire planet, and why are so many long dormant volcanoes suddenly roaring back to life? The spectacular eruption of Mt. Etna in Italy is making headlines all over the world, but it is far from alone. According to Volcano Discovery, 35 major volcanoes either are erupting right now or have just recently erupted, and dozens of others are stirring. So what is causing this upsurge in volcanic activity? Is something strange happening inside the Earth? According to the USGS, magma is “molten...
  • WATCH: In Hawaii, A 'Firehose' Of Lava Pours Into The Ocean

    NPR ^ | February 2, 2017 | Merrit Kennedy
    Researchers in Hawaii have captured dramatic footage of a "firehose" of red-hot lava plummeting down a cliff into the Pacific Ocean, sending fragments of lava and clouds of gray smoke into the sky. It's coming from the big island's Kilauea volcano, which has been erupting since January 1983. On New Year's Day, about 21 acres of rock from the Komokuna lava delta collapsed. After that, "the exposed lava tube continued to feed a cascade of molten rock down the steep sea cliff," according to the USGS Hawaiian Volcano Observatory. That's what we're looking at now.

  • Popcorn-rocks solve the mystery of the magma chambers

    Science Daily ^ | 11/2/2016 | Uppsala Universitet
    Since the 18th century, geologists have struggled to explain how big magma chambers form in Earth's crust. In particular, it has been difficult to explain where the surrounding rock goes when the magma intrudes. Now a team of researchers from Uppsala University and the Goethe University in Frankfurt have found the missing rocks -- and they look nothing like what they expected. Researchers have previously proposed that the roofs and walls of magma chamber were either melted and assimilated into the magma, or that they would sink to the bottom of the magma chamber. However, enough evidence for either of...

    US President Barack Obama has declared a slow-moving lava flow from the Pu'u O'o vent of the Kilauea volcano in Hawaii to be a major disaster, the White House said. The declaration frees up federal money to help protect local communities from the lava flow, which began moving toward homes on the big island of Hawaii on June 27 and is threatening Pahoa village.

    Ajai RajSeptember 8, 2014 Last Friday's eruption at Iceland's Bardarbunga volcano had many worried about the possible impacts of a larger eruption on air travel. Another eruption at Hawaii's Kilauea volcano has caused a state of emergency to be declared on Big Island, as lava flows from the ongoing eruption have advanced within a mile of a residential zone. That's just one example of how much danger volcanoes pose to the U.S. — and we aren't doing much about it. Compared with Iceland, the U.S. is much more vulnerable to volcanic disasters — and has been failing at monitoring these...

    Streams of lava pouring into the ocean from the Big Island have been captured in a rare video that's drawing attention from around the globe. The Kilauea Volcano has been erupting continuously from its Pu'u'O'o vent since 1983, according to Reuters, but the lava flow usually doesn't make the seven-mile journey into the ocean. Lava first started flowing into the ocean on November 25. You can track the lava's flow on the National Parks Service website. And officials are cautioning curious tourists to keep their distance. See a slideshow of the lava flow. "Ocean entries can be quite beautiful but...

    ANCHORAGE, Alaska (Reuters) - A volcano that has been erupting for several days in Alaska's Aleutian Islands may be preparing for a more explosive event, scientists said on Wednesday. Cleveland Volcano, a 5,676-foot peak located on Chuginadak Island, about 940 miles southwest of Anchorage, has been in low-level eruption since the end of July, the Alaska Volcano Observatory said. "An eruption for us is any time that magma is coming up from the surface in the ground," said John Power, scientist in charge at the observatory, a joint federal-state operation. "This is very much happening here." Chuginadak Island is uninhabited...

Dr Dario Tedesco, from the University of Naples, one of the world's leading authorities on the volcano, tries to alert the scientist whose life is at risk. Mount Nyiragongo is one of the most active volcanoes in the world. Scientists want to take lava samples from volcanoes because it can give vital clues about what is happening deep inside the planet.

    Honolulu Civil Beat ^ | March 7, 2011 | Staff
    A new vent that opened Saturday on Hawaii's Kilauea Volcano continued to erupt yesterday, throwing lava 80 feet into the air. The fissure opened up after Puu Oo crater collapsed on Saturday, sending up a giant plume of ash. The crater — and the new vent nearby — are in a remote area about 10 miles east of the Jagger Museum in Hawaii Volcanoes National Park. The fissure now measures 1.4 miles long, with lava continuing to erupt up and down the vent. This development is considered part of the larger volcanic eruption that began in 1983, and has...

From the Earth Science Picture of the Day, where this was a top pick for 2010: http://epod.usra.edu/blog/vote-2010.htmlCaption: Pumice is a glassy volcanic rock that's so full of bubbles that most examples will float on water. Reticulite is an extreme form of pumice in which the bubbles have coalesced, leaving only a tenuous reticular network of glassy lava behind in the interstitial spaces between the bubbles. While pumice is more characteristic of...

    Dumping all our nuclear waste in a volcano does seem like a neat solution for destroying the roughly 29,000 tons of spent uranium fuel rods stockpiled around the world. But there’s a critical standard that a volcano would have to meet to properly dispose of the stuff, explains Charlotte Rowe, a volcano geophysicist at Los Alamos National Laboratory. And that standard is heat. The lava would have to not only melt the fuel rods but also strip the uranium of its radioactivity. “Unfortunately,” Rowe says, “volcanoes just aren’t very hot.” Lava in the hottest volcanoes tops out at around 2,400F....

    The picture isn't that spectacular; the video (in Quicktime) is. When I saw this I knew it had to be a Geopic of the week (sorry I'm late). The movie is in real-time. Turn up the sound. If you're wondering what this is, it's a view down the throat of the Hale'maumau vent. I wonder if this will eventually rise and fill the crater floor, even if only briefly -- that would be a sight. http://hvo.wr.usgs.gov/kilauea/update/archive/2009/Jun/HMMvent_03June2009web3.mov

    Piton de la Fournaise, the Indian Ocean analog to Kilauea on the French island analog to Hawaii, started erupting on September 21. It's a cute little eruption (unlike the last one, one of Fournaise's largest), with lava fountains on the side of the crater pouring down the slope to form a pond. Picture below; the linked Web site above has to very nice videos. Turn down the volume of the top one, though.
