[S-SS03] Induced and triggered seismicity: case-studies, monitoring and modeling techniques

Wed. May 23, 2018 3:30 PM - 5:00 PM A04 (Tokyo Bay Makuhari Hall)

convener:Francesco Grigoli(ETH-Zurich, Swiss Seismological Service), Yosuke Aoki(Earthquake Research Institute, University of Tokyo), Bogdan Enescu(京都大学 大学院 理学研究科 地球惑星科学専攻 地球物理学教室, 共同), Luca Urpi(Swiss Seismological Service - ETH Zurich), Chairperson:Enescu Bogdan(Graduate Schoold of Science, Kyoto University), Aoki Yosuke, Urpi Luca(ETH-Zurich; Swiss Seismological Service)

Induced and triggered seismicity occurs in conjunction with human activities such as reservoir impoundments, mining operations, conventional and non-conventional hydrocarbon production, geothermal energy exploitation, wastewater disposal, CO2 sequestration and gas storage operations as well as volcanic and hydrogeological processes. The stability of faults is affected by external solicitations such as pore-pressure diffusion, relaxation effects and stress field perturbations related to mass and/or volume changes, dike intrusions and earthquake-earthquake interactions. A better understanding of the physical processes governing induced and triggered seismicity is thus important for assessing the risk of current and future industrial activities, including the geological disposal of nuclear waste.

The study of induced and triggered seismicity is inherently an interdisciplinary problem, which requires the combination of seismological, hydrogeological and geodetic data as well as a wide range of modeling approaches. This session covers the analysis and modeling of induced and triggered seismicity at different spatial scales and in different environments. We welcome contributions from earthquake and volcano seismology and geomechanics.

Relevant topics to be presented include - but are not limited to - new methods for microseismicity characterization (both natural and anthropogenic), spatio-temporal variations of physical parameters (including stress, pressure and temperature changes), spatio-temporal patterns of seismicity, modeling strategies and case-studies.

The goal of the session is to cover both observational, theoretical and experimental aspects on the topics summarized above.

Discussion (4:45 PM - 5:00 PM)
