Rudiger Escobar-Wolf (GMES/EPSSI) is Principal Investigator on a project that has received a $294,662 research and development grant from the National Science Foundation. The project is titled “Collaborative Research: Lahar Dynamics and Monitoring: A Multiparametric Approach Grounded in Infrasound.” This is a potential three-year project.

Lahars, or volcanic mud flows, produce infrasound (low-frequency acoustic energy) that can be detected from distances of many kilometers. As such, it is possible to remotely characterize these hazardous mud flows by tracking their flow positions and energetics through time.

This work seeks to develop infrasound analytical tools to locate where lahars initiate, how far and fast they move, and estimate their mass flow.

Toward these goals the project will deploy and maintain seismic and infrasonic instruments at Fuego Volcano (Guatemala), where lahars are common during the rainy season (April through September). Rain gauges and time lapse cameras will be installed at locations along the lahar paths to understand how lahars initiate and to validate flow characteristics through direct observation.

This award is cofunded by the PredicMon of and Resilience against Extreme Events (PREEVENTS) program.

Department and Museum Represented at Institute on Lake Superior Geology

Terrace BayTed Bornhorst, A. E. Seaman Mineral Museum executive director and interim curator, and Patty Cobin, associate museum manager, attended the 65th annual Institute on Lake Superior Geology held in Terrace Bay, Ontario, May 7-10, 2019.

Cobin was registrar for the 112 attendees of the technical sessions and those who attended one or more of the 8 pre- and post-meeting field trips. Thomas Bodden, a graduate student in geological and mining engineering and sciences department, also attended the meeting. Bodden presented a poster paper, along with co-authors Bornhorst, Florence Begue of University of Lausanne, Switzerland, and Chad Deering, assistant professor, geological and mining engineering and sciences.

Bodden’s paper was titled: “Stable isotope composition of calcite precipitated with native copper and other minerals of the Keweenaw Peninsula, Michigan.” Last year Bodden was awarded a small research grant from the Institute on Lake Superior Geology. He received an Eisenbrey student travel award at the conclusion of the meeting to help defray the cost of attending the meeting.

Earth’s magnetic field protects the planet from solar particles that would otherwise erode the atmosphere. Thus, the magnetic field is thought to be an essential factor ensuring long-term planetary habitability. Today, this geomagnetic field is powered by growth of the solid inner core. But thermal models suggest Earth has not always had a solid inner core; the time of the onset of inner core growth has ranged from 500 million to more than 2.5 billion years ago. This represents a fundamental unknown about the planet. Arguably the best way to investigate this question is to use “paleomagnetism”, the record of the ancient magnetic field trapped in rocks and crystals as they form. Such data have motivated the hypothesis that the geomagnetic field, and the magnetic shielding of the atmosphere from solar particles, almost collapsed 565 million years ago, but then the field slowly recovered. This event may record the birth of the solid inner core. This hypothesis will be tested through studies of rocks ranging in age from 800 to 500 million years old found in Australia, Canada and the United States. The collaborative work will involve a team of 5 scientists at 3 institutions (including an underrepresented minority and woman scientist), and will be integrated into education and outreach efforts at each university, including efforts to expand opportunities for first-generation and historically underrepresented individuals.

Geological and Mining Engineering and Sciences (GMES) adjunct assistant professor Luke Bowman gave a collaborative presentation titled, “Multidisciplinary, International Geological Hazards Research Experiences,” at the Geoscience and Society Summit, March 18 – 21, 2019, in Stockholm, Sweden. The Summit was part of a multi-year effort by organizers to articulate the roles of geoscientists in solving 21st Century challenges and reaching the United Nations’ Sustainable Development Goals (SDGs). The Summit was sponsored by the American Geophysical Union, Geological Society of America and the Bolin Centre for Climate Research.

Bowman presented the evolution of disaster risk reduction research by GMES students and faculty over the past three decades. The co-authors included professor and chair John Gierke, emeritus professor Bill Rose, associate professors Thomas Oommen and Greg Waite, and research assistant professor Rudiger Escobar-Wolf. The work that Bowman presented outlined a unique history of how GMES has actively broadened its faculty and student research interests to tackle societal issues in conjunction with the geophysical aspects of natural hazards in international settings.

Study by Nathan Manser Cited by World Health Organization

A study by Nathan Manser (GMES/EF) on human pathogen destruction in resource recovery systems is cited in the World Health Organization’s recent Guidelines on Sanitation and Health.

Manser ND, Cunningham JA, Ergas SJ, Mihelcic JR (2016). Modeling inactivation of highly persistent pathogens in household-scale semi-continuous anaerobic digesters. Environ Eng Sci. 33: 851-860.

The purpose of these guidelines is to promote safe sanitation systems and practices in order to promote health. They summarize the evidence on the links between sanitation and health, provide evidence-informed recommendations, and offer guidance for encouraging international, national and local sanitation policies and actions that protect public health. The guidelines also seek to articulate and support the role of health and other actors in sanitation policy and programming to help ensure that health risks are identified and managed effectively.

Simon Carn on the 2018 Ambae Eruption

Ambae Sulfur Dioxide plumeSimon Carn (GMES) was quoted in the story “From NASA Goddard Space Flight Center: ‘2018’s  Biggest Volcanic Eruption of Sulfur Dioxide,'” in sciencesprings. The story was also covered in Long Room, What’s Up with That? and Science Daily.

From NASA Goddard Space Flight Center: “2018’s Biggest Volcanic Eruption of Sulfur Dioxide”

“With the Kilauea and Galapagos eruptions, you had continuous emissions of sulfur dioxide over time, but the Ambae eruption was more explosive,” said Simon Carn, professor of volcanology at Michigan Tech. “You can see a giant pulse in late July, and then it disperses.”
