Multi-scale analyses reveals diverse triggering processes during induced earthquake sequences

Dr. Xiaowei Chen, University of Oklahoma

Abstract: In the past decade, Oklahoma experienced a large-scale earthquake experiment with significant variations of seismicity rates that are strongly correlated with injection rates from wastewater disposal. In response to the increased seismicity rate, the seismic network has been significantly expanded, providing a rich dataset to better understand the earthquake triggering processes during fluid injection. The original view of induced seismicity was simple and straightforward – increase pore pressure reduces effective normal stress, promoting fault failure. However, observations in Oklahoma suggests that triggering processes of induced earthquake sequences can be very complex, and are strongly influenced by fault structure and stress state.

In this presentation, I start with large-scale observation of seismicity migration and stress/fault distributions. Multi-scale analysis of seismicity migration allows us to derive hydraulic properties for the Arbuckle group and the crystalline basement. These parameters contributed to large-scale modeling that suggested the importance of poroelastic stress from fluid injection. With detailed analysis of the stress state of seismogenic faults, we find that fault stress state could strongly influence temporal evolution of earthquake sequences. Then, I discuss diverse triggering processes observed during several individual sequences. The Woodward sequence in western Oklahoma suggests that earthquake-to-earthquake triggering drives the fault activation. The Guthrie sequence in central Oklahoma occurred within a complex fault mesh network, and showed evidence of aseismic slip along a normal fault. These detailed observations provide a reference framework for future earthquake rupture simulations within different fault systems, and insights into the triggering processes during fluid-driven natural earthquake sequences.

Title: Deep Life: What’s Up Down There?


Abstract: Between Earth’s surface and the uninhabitable deep part of the planet, marine and terrestrial subsurface rocks and sediments comprise a vast habitat for life. The deep biosphere hosts an estimated 7×1029 microbial cells, and roughly 15% of the planet’s biomass, essentially all of which are bacteria and archaea. Because the deep Earth is so remote and survival there so challenging, we are still learning about subsurface microbes, their role in global biogeochemical cycles, as well as their community structure, metabolic potential, diversity, and distribution. This presentation will highlight methods used to sample these environments for life, the basic features of life underground, including what we know of the numbers and distribution of these cells, their activities, their functional capabilities, and the primary geological processes that control their survival. Using examples from recent research the discussion will also address some of the remaining challenges associated with studying life in the subsurface.

JSG EDGE: Enhancing Diversity in Geoscience Graduate Education

November, 11 2021

Time: 3:00 PM - 7:00 PM
Location: Virtual

The virtual JSG EDGE is designed to encourage US citizens and permanent residents traditionally underrepresented in the geosciences to apply to train with JSG faculty and research scientists whose research agendas are of interest to the students.

At the JSG EDGE 2021, students meet virtually with Jackson School of Geosciences faculty and research scientists interested in training diverse graduate students to conduct interdisciplinary geoscience research for the lasting benefit of humankind. Students will also meet with current JSG graduate students via a panel and social mixers, hear about some of the research at JSG via lightning talks by faculty and research scientists, and take virtual tours of JSG labs.
