The Lamont Earth Science Colloquium presents:
4-Dimensional Seismology: New Dynamic Perspectives on Groundwater, Geoenergy, and Geohazards
with Dr. Shujuan Mao, Assistant Professor, University of Texas at Austin.
Abstract: With climate change and population growth, humanity faces critical challenges related to water security and the energy transition. Tackling these issues requires high-resolution monitoring of subsurface fluid-rock systems (e.g., aquifers and geothermal reservoirs). In this seminar, I will introduce a novel, cost-effective, and scalable approach for aquifer monitoring using 4-dimensional passive seismology. The validity and promise of this approach will be demonstrated through case studies of aquifers across Greater Los Angeles. I will showcase how this time-lapse seismic technique offers new insights into aquifer dynamics in response to climate extremes and anthropogenic activities. I will present ongoing efforts leveraging 4D seismic interferometry to understand the dynamics in fluid-rock systems associated with geothermal and volcanic systems.
The Earth Science Colloquium Series, sponsored by Lamont-Doherty Earth Observatory and Columbia University Department of Earth and Environmental Sciences (DEES), provides a lively forum for discussing a wide variety of topics within the Earth sciences and related fields. Colloquia are attended by the full range of scientific and technical staff at LDEO. Colloquium attendance is required of all pre-orals DEES graduate students.
