  • 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.

    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...

    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...

    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....

    Background: Several months ago, a vent opened explosively in Halemaumau, the crater inside the caldera of Kileaua volcano. Halemaumau used to be famous (notably due to a description from Mark Twain) as the location of a lava lake, fairly easily accessible by visitors. The lava lake disappeared in 1924 during a series of explosive phreatic eruptions (steam and hot rock). The lake has appeared briefly since then, such as in 1967.

    When last we visited Kilauea (I think), the Pu'u O'o crater was hosting an active lava lake, and I thought there was a possibility of an overflow or a below-rim outbreak. Neither happened. Instead, the lava lake drained smoothly and a fissure eruption commenced. This is where all the action is currently. If you want to see where it's located, click the Maps link at the header link. I realized that I hadn't checked for images of this for more than a month. So I did. Below is my favorite, reduced to half-size. Click on it for full-size.

    La Reunion's famous Piton de la Fournaise volcano had a big eruption last week -- a much higher lava volume than is characteristic of this volcano.

There are also reports that there were 200-meter-plus lava fountains, VERY unusual for Piton.

    NEW YORK — Mt. St. Helens awoke Tuesday afternoon with a mild eruption, spewing a plume of steam and ash into the Washington State sky. The event was most probably was caused by growth of the new lava dome inside the crater, experts said. During such eruptions, changes in the level of activity can occur over days to months. The eruption could intensify suddenly or with little warning and produce explosions that cause hazardous conditions within several miles of the crater and farther downwind. Small lahars — a debris flow — could suddenly descend the Toutle River if triggered by...

    BANTUL, Indonesia - The Mount Merapi volcano spewed lava and hot clouds Saturday and a strong aftershock hit the region, sending fear rippling through the southern Indonesian area devastated by an earthquake only a week ago. The mountain's lava dome has swelled in the past week to 330 feet, raising fears that it could collapse, said Subandriyo, a government scientist who uses one name. That could release a highly dangerous pyroclastic flow — a fast-moving burst of high-temperature gases and rock fragments that burns anything in its path. More than a thousand aftershocks have hit the region since the 6.3-magnitude...

    HAWAII VOLCANOES NATIONAL PARK, Hawaii - About 44 acres of coastline collapsed into the ocean this week, setting loose a glowing stream of lava that shot out from the newly exposed cliffside 45 feet above the water. The plume, 6 feet in diameter, sent up a tower of steam as it hit the water and began forming a ramp of new land. The collapse of solidified lava shelf and sea cliff Monday was the largest since Kilauea Volcano began its current eruption in 1983. Jim Kauahikaua, scientist-in-charge of the U.S. Geological Survey's Hawaiian Volcano Observatory, said a collapse warning was...

    This somewhat resembles the set of a bad science fiction movie, but it's actually a lava flow on the Big Island (probably in the Kilauea vicinity) that went through a forest. Second pic is a close-up.

    WAILUKU, Hawaii (AP) -- The state has evicted a Maui woman from a lava tube she has lived in for the last three years. Karen Mayfield, 50, has pleaded innocent to three misdemeanor charges for illegal camping, disturbing a geological feature and littering. Her trial is scheduled to start May 31. Mayfield said she isn't allowed to stay in the lava tube while her court case is pending. "I really miss it out there," she said. "I really prefer living an alternate lifestyle where I can hear the wind blow and see the stars at night." Earlier this week, her...

    Imagine living in a country where three volcanoes are erupting at the same time, two others could blow in the very near future and 169 others are capable of awakening -- including scores deemed worthy of constant monitoring. Imagine living in a place where, in the past 25 years alone, communities have been wiped out by lava flows; eruptions have flattened huge expanses of land and killed people miles away; and avalanches of volcanic debris have swept people to their deaths. If you live in America, you live in such a country. . . . For about $15 million, the...

    How this happened: I was thinking of posting a picture of Mount Rushmore before the carvings (free-associated Mount Rushmore because I heard them talking about Rushmore Mall on the Weather Channel) but there aren't any quality pictures of Mount Rushmore before the carvings. Sooo... I started thinking about rock formations, thought about Devil's Tower, remembered the Giant's Causeway, and here we are:
