    19 July 2011 Last updated at 00:07 ET Help A scientist tries to get a lava sample from Mount Nyiragongo in Africa's Great Rift Valley, but gets too close to the boiling lake. 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.

    Fears Rise as Congo Volcano Spews Big Dust Cloud Sat Jul 27,11:18 AM ET By Themistocle Hakizimana GOMA, Congo (Reuters) - A Congolese city half razed by a volcano just six months ago was threatened again on Saturday as a nearby rumbling mountain spewed a massive wall of dust and ash for a second straight day. Experts said they were worried by a towering three-km (two-mile) plume of dust and ash thrown up by Nyiragongo, a dark cone-shaped mountain looming over Goma, home to 500,000 people in the Democratic Republic of Congo, many of them displaced by war, on the...

    UN finally agrees to feed Goma's starving people James Astill in Goma Wednesday January 23, 2002 The Guardian The United Nations finally announced plans to feed the destitute people of Goma yesterday, almost a week after a river of molten lava swept through the town from the erupting Mount Nyiragongo. Declaring the Democratic Republic of Congo's eastern capital safe - three days after virtually all its 350,000 residents returned - UN officials said food would be handed out today. But the continuing danger of earthquakes was highlighted when the World Food Programme's headquarters at Gisenyi, a mile from Goma, was ...

    The eruption of Mount Agung on the island of Bali has sparked worldwide media interest, yet volcanic eruptions in Indonesia are nothing new. Of the country’s 139 “active” volcanoes, 18 currently have raised alert levels, signifying higher than normal seismic activity, ground deformation or gas emissions. On a global scale, in any week in 2017, there were at least between 14 and 27 volcanoes erupting. Most observed volcanic activity takes place along the Pacific Ring of Fire, a region around the Pacific Ocean where several tectonic plates meet, causing earthquakes and a chain of what geologists call subduction zone volcanoes....

    Scientific American ^ | December 1, 2017 | By Annie Sneed
    Tens of thousands of people have evacuated their land in Bali as the nearby volcano Mount Agung angrily spits ash and its magma rises. Many Balinese hold the mountain sacred and accept its occasional outbursts as moral admonishments whereas geologists consider this activity a routine part of Earth’s behavior. But scientists have found another force - climate change - affects the frequency of eruptions. Now a new study shows even relatively minor climate variations may have such an influence. If they are right, today’s global warming could mean more and bigger volcanic eruptions in the future. The new study is...

    From MICHIGAN TECHNOLOGICAL UNIVERSITYIs it gonna blow? Measuring volcanic emissions from spaceLate last month, a stratovolcano in Bali named Mount Agung began to smoke. Little earthquakes trembled beneath the mountain. Officials have since evacuated thousands of people to prevent what happened when Agung erupted in 1963, killing more than 1,000 people.Before volcanoes erupt, there are often warning signs. Tiny earthquakes rarely felt by humans but sensed by seismographs emanate from the volcano. Plumes of water vapor rise from the crater. When the volcano begins to emit gases like carbon dioxide and sulfur dioxide, eruption may be imminent.But getting close to the...

USA coverage extends from 6:43 to 29:25 with a brief break in between (discussion of non-US activity). He makes the point that the USGS did not report a 5+ earthquake off the coast of Northern California but Alaska resources did report it. His USA predictions are mild and mostly effect west coast, Nevada, Colorado, Kansas etc. Off the coast of northern California he predicts a possible 5.1 and that the energy would transfer to movement in other US locations (smaller...

    FULL TITLE: 3 Large Earthquakes And A Major Volcanic Eruption In Mexico Spark Fears That The Big One Could Hit California Soon The portion of “the Ring of Fire” that runs along the west coast of North America is starting to shake like a leaf. As most of you already know, the outer perimeter of the Pacific Ocean is known for high levels of seismic activity, and the experts tell us that more than 80 percent of all earthquakes and more than 70 percent of all volcanic eruptions take place within the Ring of Fire. The North American section of...

    Mount Agung in Bali is experiencing unprecedented levels of seismic activity and could erupt in a “matter of hours” if tremors continue, Indonesia’s volcanology centre has said. More than 75,000 people have been evacuated in the last few days as Agung, the highest point of the island, has experienced hundreds of internal volcanic earthquakes. “Instrumentally we have never recorded such high energy or seismicity from Mount Agung,” Devy Kamil Syahbana, a seismologist from Indonesia’s centre for volcanology and geological hazard mitigation, told the Guardian. Data showed that Mount Agung experienced 844 volcanic earthquakes on Monday, and 300 to 400 earthquakes...

    In addition to the 47 volcanoes already known about currently “sleeping” under the Arctic ice, scientists have found more. They discovered 91 additional volcanoes in Antartica, now the largest volcanic region on earth. This is a big blow to those who think melting polar ice is the sole fault of humans. The project, by Edinburgh University researchers, has revealed almost 100 volcanoes. The highest discovered volcano is as tall as the Eiger, a popular peak to traverse in the Swiss Alps, which stands at almost 4,000 meters (over 13,000 ft) in Switzerland. Before this discovery, the densest concentration of volcanoes...
  • Can Volcanic Gas Levels Predict an Eruption?

    Before a volcano erupts, there are usually signs of what’s to come; small earthquakes, heat emission, and ground swelling, to name a few, have all been observed to precede eruptions. Volcanologists also monitor the changing composition of gas emissions at volcanoes in the months leading up to an eruption. However, precursory variations in gas have not yet been verified to occur in volcanoes hosting active lava lakes. To find out if volcanic gas emissions might also be used to predict eruptions at lava lake–hosting, carbon-poor volcanoes, Aiuppa et al. looked at Chile’s Villarrica volcano. Villarrica towers 2847 meters over the...

    June 6th, 1912 The morning of June 6th arrived on the Alaska peninsula to find the area which is now Katmai National Monument being shaken by numerous strong, shallow earthquakes. The most powerful volcanic eruption of the 20th Century was about to begin – but very few people knew about it. The Alaska peninsula has a low population density today, but in 1912 it was even lower. Beyond the land shaken by the earthquake activity, the beginnings of this event were almost unnoticed. On June 6th, 1912, a tremendous blast sent a large cloud of ash skyward, and the eruption...

    In the period from 2000-2015, the hole in the ozone layer shrank by more than 4 million square kilometers—nearly a billion acres—according to a new report in the journal Science. During the 1980s and into the 1990s, news of a massive hole in the ozone layer caused worldwide panic, stoked by everything from rumors of sheep being blinded by increased atmospheric radiation to the fear of a skin cancer pandemic and even comparisons to “AIDS from the sky.” Now scientists at MIT along with others have found that since 2000 the ozone hole has actually shrunk by an area half...

    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...

    Lake Sediments Record Climate Change At Cahokia INDIANAPOLIS, INDIANA —National Public Radio reports that climatologist Broxton Bird of Indiana University-Purdue University Indianapolis and colleagues analyzed layers of calcite crystals interspersed with layers of mud on the bottom of Indiana’s Martin Lake in order to learn about historic rainfall levels at Cahokia. The study suggests that beginning in the 900s, the Central Mississippi Valley received more rain than usual. And carbon isotopes found in skeletons at Mississippian cities indicate that people ate a lot of corn. “That comes at right around 950, and that’s around the time the population at Cahokia...

    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...

    A new analysis of the topography of the central Andes shows the uplifting of Earth's second highest continental plateau was driven in part by a huge zone of melted rock in the crust, known as a magma body. The Altiplano-Puna plateau is a high, dry region in the central Andes that includes parts of Argentina, Bolivia, and Chile, with vast plains punctuated by spectacular volcanoes. In a study published October 25 in Nature Communications, researchers used remote sensing data and topographic modeling techniques to reveal an enormous dome in the plateau. About 1 kilometer (3,300 feet) high and hundreds of...
