Induced and Triggered Earthquakes: Theory, Observations, Impact II

Submit an Abstract to this Session



Session ID#: 32883

Session Description:
Induced and triggered seismicity is a common phenomenon, associated with fluid injection in geothermal exploitation, wastewater disposal operations, hydro-fracturing, CO2 sequestration, hydrocarbon production, mining operations, filling of reservoirs, and other fields such as volcano-seismology. Regions with pre-existing faults are particularly sensitive. Public awareness and concern of induced seismicity has become ubiquitous in locations where subsurface exploration and storage is carried out. Regulations to passively monitor induced seismicity have generated a wealth of continuous seismic data. However, our understanding of the relationship between exploitation techniques and induced seismicity is still limited. The session is intended to provide a platform to present the latest research, field studies, theoretical and modelling aspects, and methods for seismic hazard analysis related to induced and triggered seismicity. Relevant topics include spatio-temporal variations of physical parameters in reservoirs and natural environments, patterns of seismicity, and their statistical properties.
