    Earthquake Fingerprint Scanning to Help Discern Induced Seismicity

    by Dr. Michael Brudzinski

    ABSTRACT

    Questions regarding the link between human activities and seismicity have grown with the rise in both small earthquakes and hydraulic fracturing/wastewater injection activities in the United States.  Multi-station waveform template matching can be used like a fingerprint scan to identify repetitive microearthquake sequences buried in seismic datasets.  The swarm behavior and the frequency-magnitude distribution of the sequences can be used as criteria to help discern induced seismicity from naturally occurring seismicity.  Identifying induced seismicity using this approach can be done in near real-time without the requirement of local seismic deployments or industry data (e.g., injection volumes/pressures or stimulation reports), although this additional data can be utilized if available to further build support for the designation of either an induced or natural origin.

    In Ohio, seven recent seismic swarms have been correlated temporally and spatially with either hydraulic fracturing or wastewater injection, while over a dozen less repetitive earthquakes were not and appear to be naturally occurring.  The recent case in Trumbull County helps to illustrate how applying the scanning technique on a local network can provide operators with advanced warning.  Application of this approach to a regional network in Oklahoma reveals over 90,000

    Seismic events since 2008 and the majority occur as swarms correlated with oil and gas operations.  In particular, the improved catalog highlights how felt earthquakes induced during hydraulic fracturing is more common that previously recognized.  The overall distribution of earthquakes induced by hydraulic fracturing in the central and eastern United States suggests that the proximity of the target interval to the basement increases the likelihood of induced seismicity. 

    PRESENTER

    Dr. Brudzinski earned a Ph.D. in Geophysics at the University of Illinois at Urbana-Champaign and completed an endowed postdoctoral fellowship at the University of Wisconsin-Madison before joining Miami University in 2004.  His scientific research is focused on the origins of hazardous earthquakes.  He has maintained nearly a decade-long field experiment in southern Mexico to investigate how colliding tectonic plates generate devastating earthquakes and tsunamis.  He is also helping uncover relationships between enhanced oil and gas recovery and earthquakes in the central and eastern US, focusing on recent seismicity in Ohio and Oklahoma.  He formed GeoSeismic Analytics, LLC to provide additional private consulting to industry.  His work has been featured in the New York Times, National Geographic, Time Magazine, National Review, and in an appearance on the Glenn Beck TV Show.  Dr. Brudzinski’s educational focus is on developing active e-learning courses through assessment of inquiry-based learning, student engagement, and authentic scientific experiences in computer-enable classrooms.  He has generated $1.3 million in external funding at Miami to support the integration of research and teaching efforts, including a National Science Foundation Early CAREER Award.  He has mentored over 20 students and postdocs resulting in national presentations, publications, and over $400K of student/postdoc led funding and awards.

    The Sea Without Fish: Life in the Ordovician Sea of the Cincinnati Region

    by David L. Meyer (and Richard Arnold Davis)

    ABSTRACT

    The Cincinnati Arch region of Ohio, Kentucky, and Indiana is known the world over for one of the most extensive surface exposures of undeformed fossiliferous marine limestones and shales of Late Ordovician age called the Cincinnatian Series.  This presentation was offered during the AIPG National conference The Expanding World of Unconventional Shale Hydrocarbon Resources held in Columbus in April; it will explore the major reasons for the significance of the Cincinnatian to geology and paleontology, based on four underpinnings: evolution, environment, preservation, and geologic history.  These factors are connected to the global significance of the Ordovician Period in Earth history that has been the focus of an international research effort in recent years.  An overview of some of the major groups of marine animals that inhabited the Cincinnatian sea will culminate in the reconstruction of the marine ecosystem that set a pattern for the ensuing Paleozoic. Although many aspects of the Cincinnatian ecosystem can be understood in light of the present-day oceans, the ecological structure of the Cincinnatian was unique in lacking many modern counterparts.  This unique character was important in determining the nature of the stratigraphic record and resources that are environmentally and economically significant today.   

    PRESENTER

    Dr. David Meyer grew up in Western New York, a region rich in geological and paleontological treasures, and this was the source of this interest in paleontology.  He majored in geology at the University of Michigan and graduated in 1966. He went on to graduate school at Yale, where his research interest in recent as well as fossil crinoids developed. He received his Ph.D. in 1970, following which he attended a one-year post-doctoral fellowship with the Smithsonian.  In 1975, he joined the faculty of the Department of Geology at the University of Cincinnati and began his career in teaching and research. He taught courses in paleontology, paleoecology, historical geology, coral reef geology and biology, and dinosaurs. In his research of living crinoids he has worked all over the Caribbean, and had several trips to the Western Pacific, including work in Indonesia, the Indian Ocean, Palau, and the Australian Great Barrier Reef. In 2012, he retired from full-time teaching at the University of Cincinnati; however, he is currently continuing part-time teaching and research as a McMicken Professor. His research has been supported by grants from the NSF, National Geographic Society, and NOAA.
