Abstract

In this thesis I use induced seismicity to ask some fundamental questions about the rupture physics of tiny earthquakes (i.e., Mw ≤ 0.6). I use a dataset of high quality microseismic events collected during hydraulic fracturing operations in the Horn River basin, Canada, and exploit the borehole-geophone setup, which is near the reservoir, to probe seismic events at high frequencies (i.e., > 200 Hz). I focus on the largest seismic events which are linked to a re-activated structure that extends from the stimulated shale into the underlying crystalline basement. These events show the clearest phase arrivals and the best signal to noise ratio.
