S31A:
Understanding Slow Slip and Tectonic Tremor Process Along a Variety of Deformation Boundaries I
Submit an Abstract to this Session
Session ID#: 6784
Session Description:
Slow slip phenomena refer to the release of strain energy within a period longer than it typically takes for a dynamic earthquake of the equivalent size. A wide spectrum of slow slip phenomena, including episodic slow slip events, low-frequency earthquakes, afterslip, and transient glacial movement, have been reported along different types of deformation boundaries, but their underlying physical mechanism and potential interaction with dynamic earthquakes remains elusive. In this session we aim to integrate seismic and geodetic observations on direct imaging of the slow slip environment and the transition zone, as well as field, experimental and numerical investigations on the physical mechanism of slow slip phenomena. We invite abstracts focusing on the spatiotemporal evolution of source properties of slow slip observations, and on experimental and theoretical topics that explore possible sources of pressurized fluids and the role they play in the slow slip process.
