Collective behaviors in seismology: models and observations for complexity in seismicity, crustal mechanics and faulting
Session ID#: 251479
Session Description:
The spatio-temporal patterns in seismicity —e.g. clustering, swarms, synchronization— are not fully understood in the canonical models of strain accumulation and release. Simple elements emerge from the complex multi-physics of the earthquake cycle. We seek to highlight new analytical, statistical and computational tools that better characterize these phenomena and deepen our understanding in the physical processes at play. In this session, we welcome observational, theoretical and numerical studies addressing some aspects of the complexity in seismicity and in faulting, including but not limited to: the emergent properties of seismicity, the physics of fault interactions and seismic-aseismic feedbacks, the seismic rupture and associated transient deformation processes, or the process of strain localization.
