Detection Limits and Near-Field Ground Motions of Fast and Slow Earthquakes
We investigate theoretical limits to detection of fast and slow seismic events, and spatial variations of ground motion expected from M 6 earthquakes at short epicentral distances. The analyses are based on synthetic ... -
Injection‐Induced Seismic Moment Release and Laboratory Fault Slip: Implications for Fluid‐Induced Seismicity
Wang, Lei; Kwiatek, Grzegorz; Rybacki, Erik; Bohnhoff, Marco; Dresen, Georg (Geophysical Research Letters, 2020-11-19)Understanding the relation between injection‐induced seismic moment release and operational parameters is crucial for early identification of possible seismic hazards associated with fluid‐injection projects. We conducted ... -
Laboratory Study on Fluid-Induced Fault Slip Behavior: The Role of Fluid Pressurization Rate
Wang, Lei; Kwiatek, Grzegorz; Rybacki, Erik; Bonnelye, Audrey; Bohnhoff, Marco; Dresen, Georg (Geophysical Research Letters, 2020)Understanding the physical mechanisms governing fluid-induced fault slip is important for improved mitigation of seismic risks associated with large-scale fluid injection. We conducted fluid-induced fault slip experiments ... -
Limited Earthquake Interaction During a Geothermal Hydraulic Stimulation in Helsinki, Finland
Kwiatek, Grzegorz; Martínez‐Garzón, Patricia; Davidsen, Jörn; Malin, Peter; Karjalainen, Aino; Bohnhoff, Marco; Dresen, Georg (Journal of Geophysical Research: Solid Earth, 2022-09-12)We investigate induced seismicity associated with a hydraulic stimulation campaign performed in 2020 in the 5.8 km deep geothermal OTN‐2 well near Helsinki, Finland as part of the St1 Deep Heat project. A total of 2,875 m3 ... -
Seismic and Aseismic Preparatory Processes Before Large Stick–Slip Failure
Dresen, Georg; Kwiatek, Grzegorz; Goebel, Thomas; Ben-Zion, Yehuda (Pure and Applied Geophysics, 2020-10-26)Natural earthquakes often have very few observable foreshocks which significantly complicates tracking potential preparatory processes. To better characterize expected preparatory processes before failures, we study ...
