Title: “Rumbles Beneath Your Feet: Earthquakes, Resource Exploration and Earth’s Tectonic History”
Introducer: Bibhu Mohanty
occurring on our planet. Widespread devastation can result from violent ground motion caused by seismic waves and other related phenomena such as tsunamis, landslide and volcanic eruptions. The deadly magnitude-7.7 earthquakes that hit Myanmar on March 28 further attests to the importance of seismic hazard assessment and risk mitigation. In this talk, we will first discuss some of the most devastating earthquakes in the past and their possible intersections with human history. We also explain how earthquakes fit into the broader theme of plate tectonics which revolutionized our understanding of the Earth’s evolution. We also examine how seismic waves have been used as a tool to explore the Earth’s interior, with fascinating applications from tectonics, resource exploration to subsurface monitoring.
Bio: Qinya Liu is the J. Tuzo Wilson Professor of Geophysics at both Department of Physics and Department of Earth Sciences at University of Toronto. Her research focuses on applying seismic methods to characterize subsurface structures and seismic sources across multiple scales (i.e., global, regional, exploration and laboratory scales). Her group is involved in the development of spectral-element methods (SEM) for seismic wave simulations and has applied full-waveform inversions to continental-scale structures based on both earthquake data and novel datasets such as ambinent noise and telseismic scattered waves. Her group also works on developing moment-tensor inversion methods for earthquakes and nuclear explosions based on heterogeneous background models, and has recently ventured into source characterization of induced earthquakes, microseismic events and laboratory acoustic emission.
