Thomas Oommen (GMES/EPSSI) is the principal investigator on a project that has received a $30,000 grant from the National Aeronautics and Space Administration (NASA).
GMES graduate student El Hachemi Bouali is the Co-PI on the project “Landslide Life-Cycle Monitoring and Failure Prediction using Satellite Remote Sensing.”
This is a one-year project.
Ebrahim Tarshizi, an assistant professor of mining engineering, has been nominated by the Society of Mining, Metallurgy and Exploration (SME) as a Henry Krumb Lecturer for the 2016-2017 series.
Tarshizi presentation for this year’s series is “Simulation and Animation of Marigold Mine with Dynamic Pit Operation.” SME Henry Krumb Lectures will be scheduled from October 2016 to May 2017.
John Gierke, GMES professor and department chair, is a co-director of Michigan Tech’s partnership with five universities on a three-year NATO Science for Peace and Security Programme. This international, multi-institutional project is co-directed by Professor Alessandro Tibaldi of the Department of Environment and Territory and Earth Sciences at the University of Milan-Bicocca and Dr. Nino Tsereteli of the M. Nodia Institute of Geophysics of Tbilisi State University.
The project focus is the study of natural hazards that could undermine social and geopolitical stability of a delicate Transcaucasian region located between Georgia and the breakaway region of Abkhazia, near the Enguri dam, the second highest arch dam of the world, which provides approximately half of the electrical energy for Georgia.
The US project team consists of Gierke and Michigan Tech GMES associate professor Thomas Oommen. They are advising Master’s student Maria Diletta Acciaro, who is pursuing a joint MS in Geology with Michigan Tech and her home institution, the University of Milan-Bicocca.
Their first project mission was in early November 2015 in Tbilisi with a kickoff meeting between the project scientists. The second mission, which took place last May 11-25, 2016, was focused on mapping and characterizing landslides and hillslopes surrounding the reservoir and that pose potential hazards to the safety the Enguri dam. “Landslides and rock falls are common on the steep slopes of these highly-weathered mountainous areas. Larger events could be triggered by heavy rains and seismicity,” says Gierke. He and Acciaro worked with their Georgian counterparts to measure rock and soil strength for the different surficial formations in the reservoir area.
The team is estimating the relative risk of different slopes surrounding the Enguri Dam using computer models that forecast landslide susceptibility. Their estimates are based on the topography (slope), geology, and strength properties of the soils and rocks. “One of the codes allow us to include seismicity in the forecasting and the other will let us explore rainfall intensity,” adds Gierke.

Eagle Mine is collaborating with Michigan Tech’s Mining Engineering Program on creating a custom-made simulation program with dynamic visualization to model and analyze the effectiveness of emergency evacuation plans and equipment in the operation.
“It’s just a start. We look forward to developing our relationship with the Lundin’s Eagle Mine and conducting various simulation studies, while looking for mutual benefits,” stated Ebrahim Tarshizi, the principal investigator of this research investigation.
Eagle Mine, a subsidiary of Lundin Mining, is a high-grade nickel and copper underground mine located in Michigan’s Upper Peninsula.
Research associate and curriculum development director Stephanie Tubman (Michigan Tech Mi-STAR) was lead author on two contributions appearing in the recently published monograph titled, “Geoscience for the Public Good and Global Development: Toward a Sustainable Future” (edited by Gregory R. Wessel and Jeffrey K. Greenberg, Geological Society of America Special Papers 520).
Postdoctoral research fellow Rudiger Escobar Wolf co-authored the Tubman paper titled, “The geoscientist as international community development practitioner: On the importance of looking and listening.”
Former project coordinator Essa Paterson and John Gierke (GMES) were co-authors on Tubman’s paper titled, “A Peace Corps Master’s International program in mitigation of natural geological hazards: Student outcomes and lessons learned.”
Curriculum development assistant Luke Bowman (Mi-STAR) was lead author on a paper in the same monograph titled, “University contributions to risk reduction following a disaster: A case study of reorienting natural hazards research efforts at San Vicente volcano.”
His paper was co-authored by Gierke and Agronomy Engineering Professor J. Fredy Cruz Centeno from the Universidad de El Salvador Facultad Multidisciplinario Paracentral.
Discover magazine published an article about Dean Wayne Pennington’s (COE) research on the Menominee Crack, a strange geological disruption known as a pop-up.
Major geologic transformations don’t usually happen in real time without explanation — especially in seismically quiet areas like the Upper Midwest. So, when Michigan Technological University geophysicist Wayne Pennington saw reports about a crack the length of a football field suddenly appearing in some swamp and woods in the northern area of the state’s Upper Peninsula, he assumed it was a small landslide.
Ted Bornhorst, executive director A. E. Seaman Mineral Museum and professor, is co-author of a paper recently published by the international journal Economic Geology. The publication is a result of collaboration with Dr. Kei Ikehata of University of Tsukuba, Japan who is first author of the paper. The paper is titled “Hydrothermal Native Copper in Ocean Island Alkali Basalt from the Mineoka Belt, Boso Peninsula, Japan.” Additional co-authors are K. Chida and T. Tsunogae both at University of Tsukuba.
Alesky Smirnow (GMES), is the principal investigator on a project that has received a $5,000 research and development agreement from the U.S. Department of the Interior, Geological Survey. The project is “Magnetic Petrophysics of the Menominee Iron Range.”
This is a two-year project.
Ted Bornhorst, executive director and professor, A. E. Seaman Mineral Museum recently attended the 62nd annual meeting of the Institute on Lake Superior Geology held in Duluth, Minnesota. The Institute includes geologic field trips as well as two days of technical presentations and posters. He served on the board of directors at its annual meeting. The 63rd annual meeting will be held in Wawa, Ontario and Bornhorst will be co-chair along with two Canadian colleagues.
