12Induced and triggered seismicity: Mechanisms, monitoring, discrimination and management strategies
|Conveners: Francesco Grigoli , Enrico Caffagni , Götz Bokelmann , Simone Cesca , Wolfgang Lenhardt , Beata Orlecka-Sikora
Induced and triggered seismicity occurs in conjunction with several industrial activities such as reservoir impoundments, mining operations, CO2 sequestration, geothermal energy exploitation, wastewater disposal, hydrocarbon production and gas storage operations.
While the occurrence of induced seismicity is universally recognized, the causes and mechanisms are not yet fully understood. The stress field perturbation due to external solicitation plays a significant role in inducing earthquakes; similarly, pore-pressure diffusion and relaxation effects have been recognized as plausible triggering causes.
Concerns have led regulatory agencies to set up guidelines to monitor induced seismicity using adeguate monitoring techniques. Monitoring is of primary interest for understanding physical processes governing induced seismicity. New processing methods are needed, as well as quantitative models to improve our understanding of the causal relationship between industrial operations and seismicity.
The current session focuses on recent advances in mechanisms, monitoring, discrimination, and management strategies in induced seismicity, and covers both theoretical and experimental aspects of these topics.
We welcome contributions covering the analysis and modeling of induced and triggered seismicity at different spatial scales, as well as discrimination between natural and induced events. Contributions from other fields such as in volcano-seismology, where fluid-induced seismicity is observed, are also welcome. Contributions regarding the development of new data analysis methods, and new approaches for discrimination between natural and triggered induced seismicity are particularly encouraged.
Finally, we welcome contributions on assessment and mitigation of the seismic hazard and on current regulations and management strategies in induced seismicity, discussing their implication and impact on both industrial practice and human society.
