Eruptions, Earthquakes, and Emissions

One Click for 50 Years of Earth's Activities

With one click, visitors can see the last 50 years of “Eruptions, Earthquakes, and Emissions.” Called E3, the app allows the viewer to select and learn about individual eruptions, emissions, and earthquakes as well as their collective impact. Visualizing these huge global datasets together for the first time, users can speed or slow or stop the passage of time. They can observe flat maps or globes, and watch gas clouds circle the planet. Data from Smithsonian’s Global Volcanism Program and the United States Geological Survey (USGS) feed into the app, and the datasets are available for free download. The app will update continuously, accumulating new events and additional historical information as it becomes available.

A team of experts developed the app with support from the Smithsonian Institution and the Deep Carbon Observatory, an international multidisciplinary research program exploring the quantities, movements, forms, and origins of carbon deep inside Earth. Deep Carbon Observatory scientists are studying volcanic emissions as part of this mission, and will more than triple the number of permanent volcano gas monitoring stations from 2012–2019.

    Dr. Elizabeth Cottrell is the curator-in-charge of National Rock and Ore Collections at the National Museum of Natural History at the Smithsonian Institution. Prior to that, she was director of the Smithsonian’s Global Volcanism Program. Her research focuses on understanding the long-term evolution of the planet, from the mechanism and chemical signature of planetary core formation 4.5 billion years ago, to the surface expression of Earth’s interior today at volcanoes around the globe. Cottrell is a fellow of the Mineralogical Society of America, a panelist for the National Science Foundation, a distinguished lecturer for the National Science Foundation’s Geodynamics at Rifting and Subducting Margins (GeoPrisms) program, and a member of DCO’s Task Force 2020.
