The largest volcanic eruptions are rare events but can represent a global catastrophe. Smaller eruptions may still have significant (billions of dollars) economic impacts and may affect the lives and livelihoods of large numbers of people, even in places distant from the erupting volcano (e.g., the relatively small eruption in Iceland in 2010). This project focuses on the Taupo Volcanic Zone (TVZ) in New Zealand as a case study of a large and very active volcanic system, and will focus on developing a better understanding of how the temperature and mobility of a magma body below the surface changes before, during, and after a major eruption. This study will contribute to our understanding of the volcanoes that produce such large eruptions (for example, Yellowstone volcanic system in the US), and will provide critical context for interpretation of real-time hazard monitoring at these and other active volcanoes. In addition, the project will include research experience for a K-12 teacher and development of new standard-based physics, chemistry and mathematics curriculum that will be disseminated broadly.
The Ontario Geological Survey, Ministry of Northern Development and Mines and the A. E. Seaman Mineral Museum teamed up to co-host the 63rd Annual Institute on Lake Superior Geology held in Wawa, Ontario May 8-12.
This professional meeting consisted of two days of technical sessions with 29 oral and 22 poster presentations. There were three geological field trips before the technical sessions and three after.
The meeting was attended by 137 geologists from the US and Canada. Academic institutions (58 members), government agencies (28 members), and mining and consulting companies (36 members) were well represented among attendees.
Margaret Hanson, museum assistant director, served as registrar for the meeting while Ted Bornhorst, museum executive director and professor, organized the meeting sessions, handled finances and decided on travel awards to students.
The Institute publishes technical volumes in hard copy for each meeting and offers them open-access online after the meeting is completed.
Bornhorst and Hanson co-edited the Institute on Lake Superior Geology, Proceedings Volume 63, Part 1: Program and Abstracts (97p.). They also compiled Part 2: Field Trip Guidebook (204p.).
The Institute is well regarded for its high quality field trips having recently won a national award from the Geoscience Information Society for the Outstanding Geologic Field Trip Guidebook Series.
The Institute initiated a new annual award for 2017, Pioneer of Lake Superior Geology, to recognize those individuals who made significant contributions to the understanding of the geology of the Lake Superior region primarily prior to the Institute’s awarding of the prestigious annual Goldich Medal in 1979.
The first Pioneer of Lake Superior Geology is Douglass Houghton (1809-1845). Bornhorst nominated Houghton for the award and wrote, along with Larry Molloy, President of the Keweenaw County Historical Society, the two-page biographical sketch published in the Proceedings Volume. As the first speaker for the technical sessions, Bornhorst provided the highlights of the important attributes that contributed to Houghton’s success.

Despite broad understanding of volcanoes, our ability to predict the timing, duration, type, size, and consequences of volcanic eruptions is limited, says a new report by the National Academies of Sciences, Engineering, and Medicine. Meanwhile, millions of people live in volcanically active areas around the world.
Volcanic Eruptions and Their Repose, Unrest, Precursors, and Timing (ERUPT) identifies grand challenges for the scientific community to better prepare for volcanic eruptions. Michigan Tech volcanologist Simon Carn (GMES) was an author on the report, and served with 11 other volcanologists and scientists on the Committee on Improving Understanding of Volcanic Eruptions that prepared the report. Their goal: improving eruption forecasting and warnings to save lives.
According to the NAP media release on the report, “Volcano monitoring is critical for forecasting eruptions and mitigating risks of their hazards. However, few volcanoes are adequately observed, and many are not monitored at all. For example, fewer than half of the 169 potentially active volcanoes in the US have any seismometers–an instrument to detect small earthquakes that signal underground magma movement. And only three have continuous gas measurements, which are crucial because the composition and quantity of dissolved gases in magma drive eruptions. Enhanced monitoring combined with advances in experimental and mathematical models of volcanic processes can improve the understanding and forecasting of eruptions.”
“This report was requested by NASA, NSF and USGS, the three main sources of funding for volcano science in the US, to identify some of the grand challenges in the field,” says Carn. “It was a privilege to serve on this distinguished committee and help craft a document that we hope will guide and strengthen future research efforts in volcanology.”
“The National Academies convenes committees of experts to review the current understanding of pressing issues and identify priorities for future progress in addressing the issues,” adds Michigan Tech Department Chair John Gierke (GMES). “Committee reports play important roles in formulating government policies and setting priorities for funding scientific research. Dr. Carn is a global leader in remote sensing for monitoring volcanic emissions and surely contributed a comprehensive assessment of the state of knowledge and recommend how different disciplinary fields could bring new perspectives and approaches to advance the understanding of volcanic hazards.”

The 2016– 2017 Eruption of Bogoslof Volcano, Aleutian Islands, United States
Bogoslof, a remote, mostly submarine volcano in the Aleutian Island arc began erupting in late December 2016 and activity continues as of February 2017. The Bogoslof eruption highlights several of the challenges facing volcano science. Over one month, the volcano produced numerous explosions with plumes rising 20,000–35,000 ft, posing a significant hazard to North Pacific aviation. There are no ground-based instruments (e.g., seismometers) on the volcano, and so the USGS Alaska Volcano Observatory (AVO) has been relying on distant seismometers, satellite data, infrasound, and lightning detection to monitor activity (Challenge 3). Bogoslof’s submerged vent obscures any preemptive thermal or gas signals, and infrasound and lightning are detectable only after eruptions have begun (Challenge 1). AVO has been unable to provide early warning of these hazardous events. The eruption also highlights our limited understanding of magma–water interactions and raises important questions regarding the controls on phreatomagmatic explosivity, column altitude, ash removal, and pauses (Challenge 2). In more than 20 discrete events, the emerging volcano has reshaped its coastlines repeatedly, providing snapshots of volcano–landscape interactions. The figure below shows the first evidence for an ash-rich (brown-grey) plume, almost one month into the eruptive activity.

The Daily Mail (London) published an article about the eruption of a large Russian volcano. The article quoted Tech volcano expert Simon Carn (GMES).
Stunning footage shows a giant Russian volcano violently erupting for the first time in 250 YEARS
- The 7,103ft tall (2.2km high) Kambalny volcano is in the Kamchatka peninsula in the far east of Russia
- The colossal volcano recently became active and spewed out a 60-mile long ash plume visible from space
Nasa scientists warned that the volcano may have spewed out large amounts of sulphur dioxide (SO2), which is harmful to human lungs.
The higher SO2 amounts downwind could be due to multiple factors, including variable emissions at the volcano (such as an initial burst), increasing altitude of the plume downwind or decreasing ash content downwind,
Simon Carn, an atmospheric scientist at Michigan Technological University, told the Earth Observatory.
Simon Carn (GMES) discusses sulfur dioxide emissions in an article accompanying a NASA Image of the Day showing the extent of the fires in Mosul, Iraq.
Sulfur Dioxide Spreads Over Iraq
In June 2003, atmospheric scientists at NASA’s Goddard Space Flight Center and the University of Maryland, Baltimore County, used satellites to track how much sulfur dioxide streamed into the atmosphere from a fire at a sulfur mine and processing facility near Mosul, Iraq. They calculated that the fire at Al-Mishraq, which burned for nearly a month, released 21 kilotons of toxic sulfur dioxide per day. That is roughly four times as much as is emitted each day by the world’s largest single-source emitter of sulfur dioxide, a smelter in Noril’sk, Russia.
More recently, sulfur dioxide has been lofted to higher altitudes where it may undergo long-range transport. —Simon Carn
In the News
News outlets around the world covering the Mosul, Iraq fires quoted Simon Carn (GMES) for his work in sulfur dioxide emissions. The original story was posted by NASA’s Earth Observatory along with satellite images; news outlets include ABC News, Nature World News, Yahoo News and a number of science blogs.

The Smithsonian Magazine referenced Simon Carn’s (GMES) volcanology research, which seeks to incorporate emissions data into the Smithsonian database, in a feature story along with an interactive map.
How Earthquakes and Volcanoes Reveal the Beating Heart of the Planet
Earthquakes and volcanoes can conjure up images of widespread destruction. But for those who study Earth’s deepest reaches, like Elizabeth Cottrell, a research geologist at the Smithsonian’s National Museum of Natural History and director of the Global Volcanism Program, volcanoes are also “windows to the interior.”
“Global satellite monitoring of volcanoes will transform our understanding of gas fluxes from Earth’s interior to exterior in the coming decade,” says Cottrell, who has been working along with Michigan Tech researcher Simon Carn and data manager Ed Venzke to incorporate volcanic emissions into the Smithsonian database since 2012.
