Elliz McClelland Interns for EarthScope and Presents at the American Geophysical Union Annual Meeting

Published
By

This summer, Elliz McClelland interned in the URISE (Undergraduate Research Internships in Seismology) program, funded by EarthScope (formerly known as IRIS). This internship experience gave them professional research experience, guidance about graduate schools, and the opportunity to work with an institution they’d like to work at during their career. As part of their internship experience, they will also present at the annual national American Geophysical Union (AGU) meeting in December 2023, a completely new experience for them.

During Elliz’s internship, they conducted research into a volcanic caldera using geophysics in New Mexico. Elliz worked under the mentorship of the United States Geological Survey and spent part of their summer working in the USGS office in Denver, Colorado. This internship was a multi-faceted experience where they had the opportunity to do a lot of traveling. Elliz spent their first couple of weeks performing fieldwork in New Mexico in their study area, then moved into Denver to work at the USGS office. They were also lucky enough to work on a separate USGS project where they traveled to Hawaii to help their mentor conduct field research. Their summer was full of new experiences and cultures!

The URISE internship was highly targeted toward providing research experience and preparation for graduate school. While Elliz intends on taking a least one gap year before attending graduate school, the information the internship coordinators provided them about graduate school was instrumental in making their decisions about furthering their education. 

When reflecting on the value of the URISE internship, Elliz says, “For my needs, this internship was also immensely useful in determining my career path. I ‘put my boots on the ground’, so to speak, working directly with the USGS under a position I might like to hold myself in the future. My summer experience really confirmed for me that I love doing field work and I would enjoy working for an institution like the USGS.”

In December, Elliz presented their work at the AGU national conference in San Francisco, California. This conference is one of the biggest Earth Science conferences in the nation and is an excellent opportunity for students to meet potential employers, experience the professional research conference environment, and network with fellow geoscientists. For more details about Elliz’s internship experience and the research they conducted, you can visit their summer blog at URISE. Elliz would also like to highly recommend this internship to any geoscience students with an interest in research and geophysics. Anybody can apply and prior geophysics experience is not required! You can stay updated about internship applications at URISE.

Murchek Successfully Defends Geophysics Ph.D. Research Proposal

Published
By

Jacob T. Murchek presented his doctoral research proposal defense on Friday, December 1, 2023. Advised by Dr. James DeGraff, with Dr. Benjamin Drenth, Dr. Jeremy Shannon, and Dr. Aleksey Smirnov serving as committee members. 

Murchek pictured collecting geophysical data across the Keweenaw Fault using the Lacoste Romberg Model G Gravity Meter and the Trimble differential GPS unit to create better constrained models of the subsurface geology crucial to refine the history of the Midcontinent Rift System and copper mineralization.

Title: Integration of Geophysical Data with Geologic Constraints to Infer Tectonomagmatic Controls on Mineral Systems in the Yukon-Tanana Uplands, Alaska, and Keweenaw Peninsula, Michigan

Abstract: Critical minerals are necessary for the everyday needs of modern human society and are paramount for the advancement of technology. Lithium, cobalt, nickel, and graphite are some examples of critical minerals used in cell phones, military equipment, vehicles, batteries, and other essential products. To increase domestic production of critical minerals, the U.S. Geological Survey (USGS) seeks to identify areas favorable to host deposits of such minerals through the Earth Mapping Resources Initiative. In collaboration with the USGS, the proposed research aims to identify tectonomagmatic controls of mineral systems in the Yukon-Tanana Uplands (YTU), Alaska, and along the Keweenaw Peninsula (KP), Michigan, using geophysical and geologic data to better understand the distribution and origin of such systems and to judge critical mineral potential in the two areas.

Both the YTU and KP have the potential to host critical mineral deposits, however, mineral systems in these areas are not completely understood. Critical minerals in the YTU are most likely to occur as secondary minerals associated with precious metal mineral systems. Aeromagnetic data will be interpreted, modeled, and integrated with regional geology, magnetic susceptibility measurements, and geochemical data to aid in delineating the boundary between the parautochthonous North American Basement (NAb) and allochthonous Yukon-Tanana Terrane (YTT) that underlie the YTU. Establishing a firm boundary for these terranes has major implications for understanding the origin and distribution of mineral systems across the YTU (e.g., porphyry Cu-Au, orogenic Au) and, consequently, the potential for such systems to host critical minerals. The research will emphasize developing geophysically mappable criteria for these and other mineral systems and the plutonic suites that may be associated with their deposition and enrichment. Along the KP copper district and its southwest extension, gravity and magnetic data, and possibly seismic reflection data, will be acquired to model the structure of the Midcontinent Rift System (MRS), thereby testing published cross-sectional models for the rift and the Keweenaw fault system (KFS). Better definition of the KFS is relevant to understanding migration pathways of copper-bearing hydrothermal fluids that produced economic deposits of copper and silver in the region. Quantitative geophysical modeling in the region can be tightly constrained by bedrock outcrops and rock property measurements (e.g., density, magnetic susceptibility). A better constrained subsurface model across the southeast margin of the MRS will establish a stronger tie to offshore geophysical data previously collected across Lake Superior. Such models should also improve the definition of known faults in the KFS as well as identify new faults beneath Jacobsville Sandstone, thus helping to infer mineralization pathways for copper and other elements associated with the MRS.

Title: An Investigation of Microseismicity During the 2018 Kīlauea Caldera Collapse

Abstract: The 2018 Kīlauea volcano eruption and incremental caldera collapse was accompanied by more than 60,000 seismic events cataloged by the Hawaiian Volcano Observatory as well as 62 caldera collapse events. The majority of seismicity occurred on the eastern side of the caldera between daily collapses. However, the majority of caldera subsidence occurred to the west. To understand the collapse mechanics behind this variance in subsidence and seismicity across the caldera region, repetitive waveforms and source properties can be studied.

Repeating seismic events suggests a common source that is not moving or destroyed. At Kīlauea, clusters of repeating events can indicate source processes throughout collapse cycles. REDPy, a repeating earthquake detector tool for Python, cross-correlates seismic events to determine repetition. Events are separated into families or listed as orphans if no matches are found. We used data from HVO network stations surrounding Kīlauea’s summit. Possible events were identified using an STA/LTA trigger algorithm with a long-time average trigger of 8 seconds, a short-time average trigger of 1 second, and a trigger on/off range of 1-2.5. A minimum correlation coefficient of 0.7 was used to group over 167,000 recognized events from April 29th to August 2nd into nearly 6,000 families. Of these families, 697 were chosen as ‘clusters of interest’ for including >100 events or persisting for 7 days or more. P wave first motions were manually picked for waveforms associated with clusters of interest. These clusters were then located using P wave arrival times, and focal mechanisms were modeled for viable events to learn more about their source processes and relationship to collapse mechanics.

Dilatational first motions dominate our catalog and indicate crack-closing sources with possible relationships to conduit collapse after magma withdrawal and crack closure due to fault motion. Focal mechanism models produced mismatched station polarities indicative of non-double-couple sources, further aiding the hypothesis that dominant events involve a negative volumetric component. Focal spheres show evidence of ring faulting that is likely responsible for these non-double-couple events through the motion of concave fault structures presenting as repetitive crack closure along caldera margins.

Brendan Harville Presents at the Michigan Space Grant Consortium Annual Conference in Kalamazoo, MI

Published
By

From his first weeks in the GMES Department, Brendan Harville was interested in getting involved in research. Through a handful of well-timed events in Brendan’s first semester, he seized an opportunity to submit a research proposal with Dr. Greg Waite to the Michigan Space Grant Consortium (MSGC) undergraduate fellowship to conduct research regarding “Seismic Amplitude-based Lahar Tracking for Hazard Risk Mitigation at Fuego Volcano in Guatemala.” Brendan’s proposal was selected, leading him to plan fieldwork in Guatemala with fellow PhD student Gustavo Béjar-López. Brendan and Dr. Waite used seismic data to create a model that
can locate and track how lahars propagate down drainages from Fuego’s flanks. The work took many twists and turns (as research often does!) and resulted in an improved understanding of how the morphology of Fuego and its many drainages influence lahars and their impacts. Brendan’s work was accepted by MSGC for an oral presentation at the MSGC Annual Conference on October 21, 2023. GMES student Conor Large accompanied Brendan for his presentation over MTU’s Fall Break.

Reflecting on the entire MSGC experience, Brendan says, “My experience with undergraduate research through MSGC was invaluable. I met, connected, and collaborated with many admirable and inspiring peers and mentors for which I am truly grateful for. Special experiences like these are what invigorate and propel students like me toward future goals and aspirations. I would never have enjoyed this opportunity if I hadn’t pushed through my initial fears and feelings of self-doubt.”

GMES celebrates Brendan’s accomplishment and is proud to have submitted four new MSGC proposals this week for the Consortium’s annual call.

EPSSI Seminar: Role of Subsurface Engineering and Geology in the Energy Transition World

Published
By

Mary Herrmann-Foley, MBA, returns to campus as the EPSSI Seminar guest speaker on Monday, October 23, 2023, from 4 – 5 p.m. in M&M room U113. Mary completed her Bachelor’s Degree in Geological Engineering at Michigan Tech in 1983. She continued her education at the University of Houston, earning her master’s in business administration in international finance in 1985. Currently, she serves as Manager of Central Support PetroSigns SSW application at Shell. Last fall, Mary was inducted into the Academy of Geological and Mining Engineering and Sciences. We are excited to welcome her back to campus once again!

In her talk, Role of Subsurface Engineering and Geology in the Energy Transition World, she will discuss the essential role of subsurface engineering and geology in the changing world of energy transition.

From the abstract: The world is in the midst of the first “truly global energy crisis,” the International Energy Agency (IEA) said in its World Energy Outlook in October 2022. It’s multidimensional and comes with the challenge of global warming and the need to reduce/eliminate CO2 emissions. We are all experiencing the impact of rising CO2 in the atmosphere: ocean levels rising, more intense storms, and increasing temperatures with corresponding implications on us and the environment around us. Conflicting pressures linked to continued high-energy demand, the need for energy security, and the imperative for reducing CO2 emissions are driving unprecedented renewable energy growth. This presentation will touch on the challenges related to these conflicting pressures and how existing and start-up energy companies are addressing some of these challenges through numerous renewable energy and carbon sequestration options, mainly focusing on the crucial role subsurface engineering and geology can play in this journey. Highlights of Michigan’s current situation and related business opportunities will also be discussed.

All are welcome to attend.
