Advertising of an AGU 2024 session

[Antoine, Solene L (329A)]

Dear Earthscope community,

 

We would like to advertise an upcoming session on Shallow fault zone processes at the next AGU 2024:

 

“Interested in earthquake surface deformation and faulting processes? Please consider submitting an abstract to AGU 2024 Tectonophysics session T021 - and let your colleagues know about the session. This session seeks contributions from diverse fields of geology and geophysics including geodetic and field observations, laboratory experiments, and numerical modeling. Two invited presentations will be given by Jessica McBeck (University of Oslo), and Kathryn Materna (University of Colorado Boulder).

 

Tectonophysics session T021: Shallow fault zone deformation over the earthquake cycle: observations, experiments, and models.

 

Shallow fault zones are transitional regions between deep crustal faults, where earthquake ruptures nucleate and propagate, and Earth’s free surface where earthquake ruptures may or may not terminate shallowly and generate distributed deformation in the surrounding crust. Understanding what factors mechanically control the spatiotemporal distribution of shallow fault slip and deformation throughout the earthquake cycle remains an outstanding question with significant implications for seismic and surface rupture hazard models. This session aims at bringing together complementary perspectives that investigate shallow fault zone deformation, including its sensitivity to fault and crustal rheological properties, the interplay between coseismic slip and aseismic slip (creep, afterslip), fluid interactions, and relations with the earthquake source properties. We welcome contributions with new geodetic, geophysical, and geological observations of natural faults, laboratory observations and experiments, and models (theoretical, geomechanical, kinematic and dynamic) that investigate the physics of shallow faulting and/or reproduce observations.
