Comparative investigations of Slow-to-Fast Earthquakes: Observations, Experiments, and Numerical Modeling

Session ID#: 157747

Session Description:
Both slow and fast ruptures on faults are commonly observed in a variety of tectonic environments worldwide. This session aims to identify the factors that control such slow and fast ruptures using data obtained from seismic and geodetic observations, geological fieldwork, laboratory experiments, and numerical modeling. We welcome multidisciplinary contributions that undertake comparisons among different subduction margins and other plate boundary environments to reveal the physical processes that control slow vs. fast earthquakes, and the linkages between these phenomena. By distinguishing both global and regional factors controlling the slow and fast rupture processes, an ultimate goal is to develop a conceptual model explaining their occurrence. In addition to investigations focused on fault slip, we also welcome contributions revealing slow vs. fast deformation processes in landslide and glacial environments, as these may provide important analogues to increase understanding.
