  • Deep subterranean connection between two Japan volcanoes
    on July 14, 2018 at 2:01 am

    Scientists have confirmed for the first time that radical changes of one volcano in southern Japan was the direct result of an erupting volcano 22 kilometers (13.7 miles) away. The observations from the two volcanos -- Aira caldera and Kirishima -- show that the two were connected through a common subterranean magma source in the months leading up to the 2011 eruption of Kirishima. […]

  • Using artificial intelligence to understand volcanic eruptions from tiny ash
    on June 28, 2018 at 9:14 pm

    Scientists have shown that an artificial intelligence program called a Convolutional Neural Network can be trained to categorize volcanic ash particle shapes. Because the shapes of volcanic particles are linked to the type of volcanic eruption, this categorization can help provide information on eruptions and aid volcanic hazard mitigation efforts. […]

  • 'Ring around bathtub' at giant volcano field shows movement of subterranean magma
    on June 27, 2018 at 8:04 pm

    A new study is tracing the geologic changes in the Maule volcanoes, located in a region in Chile that has seen enormous eruptions during the last million years. […]

  • Volcano music could help scientists monitor eruptions
    on June 15, 2018 at 7:45 pm

    A volcano in Ecuador with a deep cylindrical crater might be the largest musical instrument on Earth, producing unique sounds scientists could use to monitor its activity. New infrasound recordings of Cotopaxi volcano in central Ecuador show that after a sequence of eruptions in 2015, the volcano's crater changed shape. The deep narrow crater forced air to reverberate against the crater walls when the volcano rumbled. […]

  • Scientists use 4D scanning to predict behavior of volcanoes
    on June 7, 2018 at 2:10 pm

    Scientists are using the latest in 4D technology to predict the behavior of lava flows and its implications for volcanic eruptions. The results explain why some lava flows can cover kilometers in just a few hours, whilst others travel more slowly during an eruption, highlighting the hazard posed by fast-moving flows which often pose the most danger to civilian populations close to volcanoes. […]

  • New way to estimate magma beneath Yellowstone supervolcano
    on June 4, 2018 at 7:54 pm

    Researchers have found a new way to estimate how fast magma is recharging beneath the Yellowstone supervolcano.

[…]

  • Volcano 'libraries' could help plan for future volcanic crises
    on May 24, 2018 at 3:23 pm

  • Volcanic hazard scenarios: Mount Taranaki, New Zealand
    on May 3, 2018 at 6:29 pm

    Over the last 5000 years, Mount Taranaki volcano, located in the westernmost part of New Zealand's North Island, produced at least 16 Plinian-scale explosive eruptions, the latest at AD 1655. These eruptions had magnitudes of 4 to 5, eruptive styles, and contrasting basaltic to andesitic chemical compositions comparable to the eruptions of Etna, 122 BC; Vesuvius, AD79; Tarawera, 1886; Pelée, 1902; Colima, 1910; Mount Saint Helens, 1980; Merapi, 2010; and Calbuco, 2015.

  • Ample warning of supervolcano eruptions likely, experts say
    on April 30, 2018 at 5:18 pm

    Concern over the potential imminent eruptions of Earth's supervolcanoes, like Taupo in New Zealand or Yellowstone in the United States, may be quelled by the results of a new study suggesting that geological signs pointing to a catastrophic eruption would be clear far in advance. […]

  • After a volcano erupts, bird colonies recover
    on April 25, 2018 at 5:18 pm

    Where do seabirds go when their nesting colony is buried by a volcano? In 2008, the eruption of the Kasatochi volcano in the Aleutian archipelago provided a rare opportunity to track how the island's crested and least auklet populations responded when their nesting colony was abruptly destroyed. As a new study shows, the birds were surprisingly adaptable, establishing a new colony on freshly created habitat nearby in only four years. […]

  • Scientists decipher the magma bodies under Yellowstone
    on April 16, 2018 at 10:56 pm

  • Ash from dinosaur-era volcanoes linked with shale oil, gas
    on March 13, 2018 at 2:17 pm

    Nutrient-rich ash from an enormous flare-up of volcanic eruptions toward the end of the dinosaurs' reign kicked off a chain of events that led to the formation of shale gas and oil fields from Texas to Montana. […]

  • A new discovery that makes possible prediction immediately before plasma loss
    on March 1, 2018 at 3:36 pm

    In phenomena occurring in nature and in society, it is often commented that "Something may happen at any time, but it is difficult to predict when that something may occur." Solar flares, volcanic eruptions, extreme rainfall, and economic crises are examples of this. Such cases are called sudden phenomena. Prediction of sudden phenomena is one of the important issues in physics. By comparing physical processes related to sudden phenomena by researchers from various fields, new research is being initiated in which we fully understand sudden phenomena and what we understand leads to predictions of those phenomena. […]

  • Another clue for fast motion of the Hawaiian hotspot
    on February 27, 2018 at 2:07 pm

    Recent studies have suggested that the Hawaiian hotspot moved relatively quickly southward in the period from 60 to about 50 million years ago. This hypothesis is supported by a new study. Researchers have evaluated new rock dating of the Rurutu volcanic chain and added data from the Hawaiian-Emperor chain and the Louisville chain. It shows that the Hawaiian-Emperor hotspot displays strong motion between 60 and 48 million years ago. […]

  • New insight into how magma feeds volcanic eruptions
    on February 22, 2018 at 3:35 pm

    Researchers have provided new insights into how molten rock (magma) moves through the Earth's crust to feed volcanic eruptions. Using laboratory experiments involving water, jelly and laser imaging, researchers were able to demonstrate how magma magma flows through the Earth's crust to the surface through magma-filled cracks called dykes. […]

  • Scientists eavesdrop on volcanic rumblings to forecast eruptions
    on February 16, 2018 at 7:26 pm

    Sound waves generated by burbling lakes of lava atop some volcanoes point to greater odds of magmatic outbursts. This finding could provide advance warning to people who live near active volcanoes. […]

  • Giant lava dome confirmed in Japan's Kikai Caldera
    on February 9, 2018 at 3:07 pm

    Researchers have confirmed that a giant lava dome was created in the Kikai Caldera, south of Japan's main islands after the caldera-forming supereruption 7,300 years ago. The dome is in the world's largest class of post-caldera volcano, with a volume of over 32 cubic kilometers. It is possible that currently a giant magma buildup may exist under the Kikai Caldera. […]

    A study of a New Zealand volcano suggests that a volcanic system's response to tidal forces could provide a tool for predicting a certain type of eruption. […]

  • Tiny crystals could help predict volcanic eruptions
    on January 23, 2018 at 3:19 pm

    They can be as small as a grain of salt, but tiny crystals that form deep in volcanoes may be the key for advance warnings before volcanic eruptions. Volcanologists have said the research provided new information that could lead to more effective evacuations and warning communications. […]

  • Large volcanic island flank collapses trigger catastrophic eruptions
    on January 18, 2018 at 7:29 pm

    New research not only implies a link between catastrophic volcanic eruptions and landslides, but also suggests that landslides are the trigger. At the heart of Tenerife and standing almost 4 km high, Teide is one of the largest volcanoes on Earth. Over a period of several hundred thousand years, the previous incarnations of Teide have undergone a repeated cycle of very large eruptions, collapse, and regrowth. […]
