  • New Findings Suggest Cryovolcanoes on Pluto

    On November 9th, New Horizons mission geologists presented evidence that Pluto’s largest and most distinctive mountains might indeed be cryovolcanoes, or ice volcanoes, that are likely to have been active in Pluto’s recent geological past. The findings are just one of over fifty new reports of exciting discoveries about Pluto, revealed just four months after…

  • Ecuadorean Eruption Sparks Fears of Glacier Floods

    Ash erupted from Ecuador’s glacier-covered Cotopaxi volcano last week after seventy quiet years. The debris shot five kilometres into the air, covering homes, cars, fields and roads as it descended, according to the Independent. Patricio Ramon, of Ecuador’s Instituto Geofísico, said the eruption was phreatic, meaning that molten rock encountered water, creating a forceful release of…

  • Volcanoes and Glaciers Shape Alaskan Landscape

    Volcanic eruptions mark the beginnings of new landscapes. Ash and lava cover existing vegetation and map out a fresh terrain. Though researchers understand how volcanic landscapes evolve over centuries, there is little understanding of how volcanic eruptions have influenced the geomorphology, or the relationship between the Earth’s surface and geological structures, according to Christopher F. Waythomas, from…

  • Photo Friday: Mount Adams

    Mount Adams, the second highest mountain in the U.S. state of Washington, is a potentially active volcano in the Cascade Range. Mount Adams was active from about 520,000 to about 1,000 years ago. During the past million years, it has generated considerable eruptive materials. Mount Adams is also home to 12 officially named glaciers. Most…

  • Volcanic Eruption Leaves Dogs Stranded and Hungry

    As communities pick themselves up from a series of volcanic eruptions in southern Chile, stories of heartbreak and happy reunions emerge. Last week, glacier-covered Calbuco erupted three times, displacing thousands of local residents and animals. The eruptions sent ash 20 kilometers into the air, according to the BBC,  and triggered a series of mudslides, which followed the…

  • Round-Up: Melt Music, An Artist’s View, and Eruptions

     Salvatore Vitale’s Glacier Art  “This is the beginning of a project that aims to explore the powerful nature of a living creature in constant evolution. I want to show how such a powerful creature can be so fragile. In those pictures you can see their magnificence, but at the same time all their fragility.” See…

  • Photo Friday: Volcanoes in Ecuador

    Ecuador has a series of beautiful cone-shaped volcanoes along the Andes. This week, GlacierHub features three volcanoes from Ecuador: Cayambe, Chimborazo, and Tungurahua. Cayambe, locating in the Cordillera Central, is a Holocene compound volcano. Chimborazo, locating in the Cordillera Occidental, is the highest mountain in Ecuador. These two volcanoes are currently inactive. On the other…

  • Will An Icelandic Volcano Erupt Under A Glacier In 2015?

    A group of well-placed observers have warned the world about the possibility of a major volcanic eruption in Iceland in 2015. Steen Jakobsen, the chief economist of the Danish trading and investment firm Saxo Bank, and the bank’s strategy team have issued their “Outrageous Predictions” for the coming year. They state that these predictions are…
