Session ID#: 31263
Session Description:
The knowledge of in situ stresses is important for a variety of applied and fundamental problems in geosciences, including large-scale tectonics, fault mechanics, reservoir geomechanics, and stability of engineering structures. In recent years, significant improvements in the stress field analysis have been driven by the need to address seismic hazards, both natural and human-induced, but in situ stress information remains sparse, especially offshore. While stress is known to vary consistently at regional scale, local variations are often observed, and remain challenging to predict and quantify. In addition, temporal evolution of in situ stresses needs to be better understood for accurate assessment of seismic hazard and deformation processes. We invite results on recent in situ stress observations, as well as experimental and modeling studies, which advance our understanding of stress patterns and heterogeneity in the shallow crust, and advance our capability to evaluate and predict in situ stresses.
