    Study finds Arctic seabed afire with lava-spewing volcanoes The Arctic seabed is as explosive geologically as it is politically judging by the "fountains" of gas and molten lava that have been blasting out of underwater volcanoes near the North Pole. "Explosive volatile discharge has clearly been a widespread, and ongoing, process," according to an international team that sent unmanned probes to the strange fiery world beneath the Arctic ice. They returned with images and data showing that red-hot magma has been rising from deep inside the earth and blown the tops off dozens of submarine volcanoes, four kilometres below the...

    QUITO, Ecuador - A volcano on the largest of the Galapagos Islands has begun erupting and authorities are evaluating possible dangers to the island's famed plant and animal life, officials said Friday. Rangers and tour guides spotted lava flowing down the northeastern flank of the Cerro Azul volcano on the seahorse-shaped island of Isabela late Thursday, the Galapagos National Park said in a statement. Ecuador's Geophysics Institute said that satellite data and a flyover of the island by park officials showed a "small amount of ash" coming out of the volcano, located on the southwestern edge of the island.

    PARIS (AFP) - A powerful volcano erupted under the icesheet of West Antarctica around 2,000 years ago and it might still be active today, a finding that prompts questions about ice loss from the white continent, British scientists report on Sunday. The explosive event -- rated "severe" to "cataclysmic" on an international scale of volcanic force -- punched a massive breach in the icesheet and spat out a plume some 12,000 metres (eight miles) into the sky, they calculate. Most of Antarctica is seismically stable. But its western part lies on a rift in Earth's crust that gives rise to...

The cloud reached a height of up to two kilometres over the 5,400- metre mountain, the national disaster protection centre said Saturday. Ash rained down on some areas near the volcano and an area of 12 kilometres around the mountain was blocked off. The volcano has been active for some time, and steam cloud has become an ongoing sight over its peak.

    JAKARTA, Indonesia — Anak Krakatau, built on the same lava plume as the Krakatoa volcano that killed tens of thousands in 1883, continued to spew lava, hot gas and rocks Thursday into the Sunda Strait between the Indonesian islands of Java and Sumatra. Anak Krakatua, or "Child of Krakatoa" in the official Indonesian language, rose from the water in 1930 at the same spot where Krakatoa had blown itself apart. Elsewhere in Indonesia, the government lowered the alert status of the Kelud volcano, meaning that thousands of people who fled its slopes for government shelters can return home.
  • Geology Picture of the Week, Nov. 4-10, 2007: Kilauea Keeps Glowing and Flowing

    11/08/2007 1:29:26 PM PST · by cogitator · 11 replies · 63+ views
    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.

    How a Volcano Eruption Wiped Away Summer by Michael Sullivan Jessica Goldstein, NPRFor more than two decades, volcanologist Haraldur Sigurdsson has been researching the volcanic eruption of Tambora. By studying layers of soil, he can decipher the history of the explosion. The biggest volcanic eruption ever recorded in human history took place nearly 200 years ago on Sumbawa, an island in the middle of the Indonesian archipelago. The volcano is called Tambora, and according to University of Rhode Island volcanologist Haraldur Sigurdsson, the eruption is one of the most overlooked in recorded history. Tambora's explosion was 10 times bigger than...

    Indonesia on top alert for volcanic eruption Thursday, October 18, 2007 By Heri Retnowati, Reuters KEDIRI, Indonesia -- Fears of an imminent eruption prompted the evacuation of thousands of residents near Indonesia's Mount Kelud on Wednesday, but many flouted the order and stayed at their homes around the rumbling Javanese volcano. The alert on the volcano, one of Indonesia's deadliest and located 90 km (55 miles) southwest of its second-largest city, Surabaya, was raised to maximum late on Tuesday, meaning it could erupt within 24 hours. Authorities had ordered the evacuation of more than 100,000 people from a 10-km (6-mile)...

    JAKARTA, Indonesia — Indonesia warned that one of its most deadly volcanos was poised to erupt and ordered nearly 30,000 villagers living along the mountain's slopes to evacuate late Tuesday. Mount Kelud, which has been rumbling for weeks, was placed on the highest alert level, meaning scientists believe a major eruption is imminent, said a posting on the government-run volcanology center Web site. The status requires local authorities to begin evacuations. Surono, a top scientist at the center, said all people living within 10 kilometers (6 miles) of the peak must leave. Authorities started transporting some away from the danger...

    Indonesia late Tuesday raised the status of a volcano on Java island to the highest alert level and recommended people evacuate the area immediately. Officials have advised residents living within a 10-kilometre (6.2-mile) radius of Mount Kelut to leave, with the Indonesian volcanology and geology disaster management centre saying the highest alert level status meant "an eruption is possible within 24 hours." The agency said on its website it raised the alert level "based on the seismic activity, deformation, visual observation and temperature of crater lake... at 17.15 WIB, 16 October 2007." Volcano monitoring post head Kristanto told a national...

    A two-topic post. First, you may have heard "Andromeda Strain" type reports of a meteor impact in Peru that reportedly caused illness in 300 people or so. The reports were unclear; some doubted there even was a meteor at all. Well, there was. The linked article in the header is about it; apparently the meteor (meteorite when it hit, of course) hit where the water table was shallow, causing some steaming. Analysis has confirmed the extraterrestrial origin, and maybe about 30 people were bothered by it. This is a summary of the article; read the whole thing for the more...

    TORONTO: A volcano has erupted on a tiny island off the coast of Yemen, spewing lava and ash hundreds of feet into the air, a Canadian naval vessel near the island in the Red Sea reported. The Yemeni government asked NATO to assist in searching for survivors. Ken Allan, a Navy Public Affairs with the Canadian Armed Forces, said a NATO fleet just outside the territorial waters of the island Jazirt Atta-Ir reported seeing a "catastrophic volcanic eruption" at 7 p.m. local time (1600 GMT) Sunday. The 2-mile-long (3-kilometer-long) island is about 70 miles (115 kilometers) off the coast of...

    Two things: one, in August a fissure eruption took place in the highly active African Rift Valley in Ethiopia. It was initially detected as a cloud of sulfur dioxide gas. Not a whole lot of pictures of this place; it's described as an "uplifted segment of a mid-ocean ridge spreading center". So an eruption here is like seeing what happens normally deep in the ocean. Here's the view from space. and two, I discovered this very cool time-lapse movie of the recent short-lived lava lake in the Pu'u O'o crater of Kilauea. Very fun to watch. Episode 57 West Vent...
