Dear EarthScope Community,
We kindly invite you to submit an abstract to the AGU session 'S009: Bridging the gap between laboratory and field observations of earthquake nucleation.' The abstract submission deadline is July 31, 2024.
The session link: https://agu.confex.com/agu/agu24/prelim.cgi/Session/227929
The Session Abstract:
Earth scientists have long sought to document and understand any physical processes that precede large earthquakes. Numerical models and laboratory experiments show that unstable frictional slip is often preceded by some form of aseismic creep. These data further show that this localized region of aseismic creep along the fault must reach a critical length scale, often termed h*, before dynamic rupture can proceed. However, the physics that control the nucleation process on natural faults and its connection to observable quantities prior to large earthquakes is not well understood. This session aims to help bridge the gap between laboratory and field observations of earthquake nucleation and its associated length scale. We encourage studies focused on geodetic observations of pre-seismic fault creep and slow-slip, in-situ fluid injection experiments, and foreshock sequences. We also welcome submissions from laboratory and modeling studies that focus on understanding the physical mechanisms that control earthquake nucleation.
Conveners:
David Chas Bolton (UT Austin)
Gregory C McLaskey (Cornell)
Camilla Cattania (MIT)
Piero Poli (U of Padova)
