Exciting news! We're transitioning to the Statewide California Earthquake Center. Our new website is under construction, but we'll continue using this website for SCEC business in the meantime. We're also archiving the Southern Center site to preserve its rich history. A new and improved platform is coming soon!

AGU Session S017: Microseismicity and fault slip: observations, modeling and experiments

Dear Colleagues,

We would like to invite you to submit an abstract to our session on microseismicity and fault slip at the AGU 2022 Fall meeting in Chicago. The deadline for abstract submission is Wednesday, August 3rd.

Session link: https://agu.confex.com/agu/fm22/prelim.cgi/Session/157916

S017: Microseismicity and fault slip: observations, modeling and experiments

Session description:
Together seismic and aseismic slip consumes the total fault slip budget and the slip mode partition is imprinted in its microseismicity. The spatiotemporal evolution and statistical characteristics of microseismicity can reveal the complex fault zone architecture and multiple physical processes involved in fault slip. However, several processes remain enigmatic.  How do swarms relate to aseismic slip in different tectonic environments? What is the interplay of seismic and aseismic slip along heterogeneous faults? How does this vary over time? Recently, novel microseismicity analysis and advanced monitoring systems have allowed us to resolve high-resolution physical processes of fault slip, fault zone architecture, and material properties.

In this session, we welcome submissions of novel microseismicity analysis approaches; interdisciplinary observations of fault structure, fault slip, and microseismicity; short and long-term studies of spatiotemporal changes in fault slip modes and mechanical properties at different tectonic settings; and theoretical developments from numerical modeling and laboratory experiments.

Invited speakers for the session include:
Pierre Dublanchet (MINES ParisTech, PSL Research University) 
Jessica Hawthorne (University of Oxford)

**Reminder:
This year’s AGU format will again be hybrid, so presentations can be given online remotely. First authors can submit up to two contributed abstracts in two different sections.

We look forward to seeing you (either in person or virtually) in Chicago!

Cheers,

Conveners:
Jianhua Gong, Scripps Institution of Oceanography
Heather R Shaddox, University of California, Berkeley
Eric Beaucé, Lamont-Doherty Earth Observatory
Yifang Cheng, University of California, Berkeley

AGU Session S015: Mechanical complexity and structural heterogeneity in diffuse fault zones, observation, modeling and experiments

Dear Colleagues,

We would like to invite you to submit an abstract to our session on the complexity in diffuse fault zones at the next AGU 2022 Fall meeting in Chicago. The deadline for abstract submission is Wednesday, August 3rd.

S015 - Mechanical complexity and structural heterogeneity in diffuse fault zones: observation, modeling and experiments

https://agu.confex.com/agu/fm22/prelim.cgi/Session/161379

Session description:

Multiple scales, multi-physics interactions and nonlinearities govern earthquake source processes, rendering the understanding of how faults slip a grand challenge of seismology. Earthquake fault zones are more complex, both geometrically and rheologically than an idealized infinitely thin plane embedded in linear elastic material. Complex volumetric failure may lead to complexity in the nucleation process (e.g., instantaneous vs.cascading ), rupture styles (e.g., pulses or cracks, sub-Rayleigh vs.super-shear), slip distribution and energy balance. A realistic understanding of co-seismic, post-seismic and interseismic slip across diffuse fault zones should account for multi-physics coupling, nonlinear visco-elasto-plastic rock rheologies, natural heterogeneities, etc. Furthermore, diffuse fault zones evolve as potentially hierarchical fault structures over space and time.

This session encourages contributions shedding light on, but not limited to, volumetric faulting processes across different scales in both space and time. We welcome interdisciplinary and focused contributions that explore observations, laboratory experiments, numerical modeling and theoretical studies. 

Invited speakers for the session include:

Ahmed Elbanna (University of Illinois Urbana-Champaign)
Jessica Ann McBeck (University of Oslo)

Reminder:

This year’s AGU format will again be hybrid, so presentations can be given online remotely. First authors can submit up to two contributed abstracts in two different sections.

We look forward to seeing you (either in person or virtually) in Chicago!

Cheers,

Conveners:
Duo Li, Munich University
Yifang Cheng, University of California, Berkeley
Yihe Huang, University of Michigan

AGU Session S008: Exploiting the Ambient Seismic Field: Opportunities From New Sources, Methodologies and Instrumentations

Dear collogues,

We would like to invite contributions to our AGU session: S008 - Exploiting the Ambient Seismic Field: Opportunities From New Sources, Methodologies and Instrumentations

Description:

The ambient seismic (noise) field has been proven to contain a wealth of information about the Earth's structure and its time-varying properties. Recent advances in seismic instruments and technology (e.g., Fiber Optic Sensing systems and Large-N arrays, both onshore and offshore) offer new opportunities to improve our perception of the noise wavefield. This session invites presentations utilizing the seismic ambient field from all types of sources, including microseisms, storms, earthquake coda, traffic, mining, or other human activities. Contributions to theoretical and methodological developments (such as spatial localization of scattering/seismic property changes, extraction of body waves, non-ideal source distribution studies, high-order correlations, and the use of machine learning algorithms) are particularly welcomed. We also encourage noise-based applications on various topics that image or monitor seismic velocity, ground motions or attenuation properties of the Earth (and other planets) related to tectonic, magmatic, environmental, or anthropogenic activities.

As a reminder, this year’s AGU will be hybrid and first authors can submit up to two contributed abstracts in two different (co-listed) sections. The abstract deadline is August 3, 2022 at 11:59 EDT. To submit an abstract to our session please go to: https://agu.confex.com/agu/fm22/prelim.cgi/Session/162682

Warm regards from the conveners:

Shujuan Mao, Stanford University
Yixiao Sheng, Université Grenoble Alpes
Loïc Viens, University of Michigan
Aurélien Mordret, Université Grenoble Alpes
