  • The Restlessness of Cotopaxi: A “Benevolent” Eruption

    On August 14, 2015, Ecuador’s glacier-capped Cotopaxi erupted for the first time since the 1940s. A billowing plume of ash rose early in the morning and grew through the day, reaching heights of over three miles. Two small eruptions rained ash on the southern outskirts of Quito, Ecuador’s capital 45 kilometers from the volcano. These…

  • Using Film to Reduce Risk on Volcanoes

    For people to cope with environmental hazards, they need to understand threats – a key step that can lead to behavior change. A recent paper by Anna Hicks et al., published in the International Journal for Disaster Risk Reduction, describes the importance of communicating glacier hazards and other risks. The authors made videos and then assessed…

  • Roundup: Hazard Films, Water Scarcity, and Peace Building

    Roundup: Films, Water and Peace   Films Raise Awareness in Volcanic Regions From Science Direct: “The medium of film is well established for education and communication about hazardous phenomena as it provides engaging ways to directly view hazards and their impacts… Using volcanic eruptions as a focus, an evidence-based methodology was devised to create, use, and…

  • Photo Friday: Volcanic Readiness in Colombia

    The Volcanic and Seismological Observatory of Manizales has recently conducted several workshops on volcanic risk with communities in the vicinity of Nevado del Ruiz, a glacier-covered volcano in Colombia that showed signs of renewed activity earlier this year. The workshops prepare communities to react to volcanic hazards like ash and lahars, the latter of which…

  • Iceland’s fire decimates its ice: Eyjafjallajökull

    A new scientific study investigates the interactions between the Icelandic volcano Eyjafjallajökull’s lava flow and the overlaying ice cap, revealing previously unknown subglacial lava-ice interactions. Six years after  the eruption, the volcano is revisited by the author of the study, Björn Oddsson, a geophysicist with Iceland’s Department of Civil Protection and Emergency Management. He and…

  • Photo Friday: Eruption at a Glacier Volcano in Russia

    Klyuchevskoy, a glacier-covered volcano on the Kamchatka Peninsula in eastern Russia, is erupting. The volcano, 4,750 meters in elevation, has had a history of extensive activity over the last 7,000 years. It has been emitting gas, ash and lava since April 3. Several organizations are closely monitoring its eruption. They note that ash explosions reaching 6 to 8 kilometers in height could occur at…

  • Photo Friday: Volcanoes of the Kamchatka Peninsula

    The Kamchatka Peninsula, located in remote Far East Russia, is part of the “Ring of Fire” and is known for its volcanic activity. The 102,400 square mile region has the highest concentration of active volcanoes in the world. The Klyuchevskoy volcano is one of the seven active glacier-capped volcanoes in the remote region. At a towering…

  • Assembling Stories of the 2010 Volcanic Eruption in Iceland

    Like many other people, I was affected by the eruption of Mt. Eyjafjallajökull six years ago.  I have begun a project which focuses on the mountain, a glacier-covered volcano in southern Iceland, and its dramatic eruption.  I am writing to invite you and others to contribute stories about this event to the project, which is titled Volcanologues.…

  • A Glacier-covered Volcano in Chile: Will It Erupt Soon?

    Several recent events suggest that a set of glacier-covered volcanoes in the southern Chilean region of Bío-Bío, which have been showing increasing activity since December, may be likely to erupt.  The three mountains, known as the Nevados de Chillán, reach over 3200 meters in elevation, and have a set of glaciers totaling over 2 square kilometers in…

  • Roundup: Gloomy Glaciologist, Icy Blasts, and New Models

    Glaciologist Causes Chills with Not So Icy Predictions “How does being the one to look at the grim facts of climate change most intimately, day in and day out, affect a person? Is Box representative of all of the scientists most directly involved in this defining issue of the new century? How are they being…
