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!

1. S010 Earthquake Ground Motion Simulation (Rupture Dynamics and Seismic Wave Propagation): Theory, Validation and Application
--------------------------------------------------------------------------------------------------------------------------------
Dear Colleagues,

Please consider submitting an abstract to the session below at the 2019 AGU Fall Meeting in San Francisco.

AGU Session S010: Earthquake Ground Motion Simulation (Rupture Dynamics and Seismic Wave Propagation): Theory, Validation and Application

The session will bring together researchers with new results from development, verification and validation of numerical ground motion simulations based on dynamic rupture and seismic wave propagations, and their applications in real earthquakes. Examples may include but not limit to 1) macro- or microscopical fault geometry, 2) plasticity adjacent to faults or sites, 3) branched or segmented faults, 4) intrinsic and scattering attenuation, and 5) ground surface topography. We also encourage results of cutting-edge techniques in HPC.

Invited Speakers:

Eric Dunham (Stanford University), Xiaofei Chen (Southern University of Science and Technology)

Abstract submission deadline: Wednesday, 31 July 2019 https://agu.confex.com/agu/fm19/s/papers/index.cgi?sessionid=78152

We look forward to seeing you in San Francisco!

Best Regards,

Conveners:

Yongfei Wang (Southern California Earthquake Center)
Kyle Withers (United States Geological Survey)
Feng Hu (University of Science and Technology of China)
Thomas Ulrich (Ludwig Maximilians University of Munich)

2. S011 Earthquakes cascade and Earthquake Hazard in the Italian Apennines: Ten Years After L’Aquila
----------------------------------------------------------------------------------------------------------------------------------------------

Multiple M6+ earthquakes have shaken the Apennine Mountains of central Italy over recent decades (Colfiorito 1997, L’Aquila 2009, Amatrice-Visso-Norcia 2016), making it among the most active areas of Europe with very high vulnerability leading to tragic losses. Advances in seismology, terrestrial-space geodesy and geology make this a natural laboratory for investigating extensional tectonics. Many questions about multiple and close occurrence of shallow normal faulting earthquakes and the hazard they pose remain unanswered. How and were do they nucleate and propagate across complex fault networks? What are the roles of crustal fluids in the triggering of seismicity?

This session invites contributions from all relevant fields (seismology, geodesy, hydrology, tectonics and laboratory), addressing questions of earthquake mechanics (nucleation, propagation), fluid diffusion, interactions and forecasting. The aim is to critically examine the current understanding to identify future research directions needed to better assess the seismic hazard of this and in similar extensional settings.
Conveners: Christophe Voisin, Enrico Serpelloni, Lauro Chiaraluce, William Ellsworth

3. S031 Resolving the Complexity of Earthquake Processes
----------------------------------------------------------------------------------
Please consider submitting an abstract to our AGU 2019 session (deadline for submission July 31!)

S031 - Resolving the Complexity of Earthquake Processes
Our collective understanding of earthquake processes has seen great progress through combined modeling efforts across multiple temporal and spatial scales, the inclusion of diverse datasets, and the comparison of modeling results with numerical and laboratory experiments. However, our interpretations of earthquake source processes remain limited due to the remote nature of observations, our incomplete knowledge of the Earth's interior, and potential modeling uncertainties or biases imposed by our prior assumptions.
This session invites contributions aimed at studying earthquake processes through both kinematic source imaging and numerical modeling approaches. We welcome studies focused on the spatio-temporal complexity of on-fault processes and the relative impact of fault geometry, roughness, fluids and bulk heterogeneity, within the context of individual ruptures as well as earthquake sequences. We solicit contributions exploring the implications of modeling uncertainties and resolution limitations in our interpretation of earthquake rupture complexity, within the scope of numerical, laboratory and observational studies.

4. T004 Advances in Methods for Observing and Modeling Seismic and Aseismic Processes:
------------------------------------------------------------------------------------------------------------------------------

Dear Colleagues,

Please consider submitting an abstract to our AGU 2019 Fall Meeting session, "T004 - Advances in Methods for Observing and Modeling Seismic and Aseismic Processes"

The session description is as follows:

Our ability to resolve aspects of the earthquake cycle continues to improve with the ongoing development of new geodetic and modeling techniques. To understand short-term and long-term tectonic processes in a complex earth, it is crucial to 1) correctly separate the contributions made by seismic, aseismic and non-tectonic deformation in data, and then 2) link these observations to fault and bulk processes with a view of their spatiotemporal complexities and interactions. We welcome new contributions on: improved methods detect the signals of interest, new techniques to invert these signals for robust interpretations of the physical processes driving them (e.g. seismic vs. aseismic slip, off-fault deformation, etc.), advances in modeling these processes using realistic physics, and any combination of these and similar topics. The aim is to provide an environment in which the observational and modeling communities can discuss our understanding of seismic and aseismic processes and the development new approaches.

Conveners:
Kali Allison, University of Maryland College Park
Chris Rollins, Michigan State University
Jessica Murray, US Geological Survey
Adriano Gualandi, California Institute of Technology

The abstract deadline is July 31, 2019 at 23:59 EDT. You may submit an abstract to this session using the following URL: https://agu.confex.com/agu/fm19/prelim.cgi/Session/79655

5. MR028 Rock Damage in Fault Zones
--------------------------------------------------------

Dear all,

We would like to bring to your attention the following session at the 2019 AGU meeting in San Francisco entitled “Rock Damage in Fault Zones (MR028)”. We are looking to attract scientists who study deformation along and off-fault using field, numerical, experimental and observational approaches.
Convenors
François Renard, University of Oslo
Sarah Incel, Ruhr University, Bochum
Giulio di Toro, University of Padova
Yehuda Ben.-Zion, University of Southern California

Summary: Rock damage in fault zones is observed in many continental regions and is inferred in subduction zones. The damage modifies earthquake rupture properties and the evolution of seismic sequences. Geophysical data indicate km-wide damage zones along plate boundaries in the upper crust, while observations of fossil earthquakes show narrow cm-thick damage zones in the lower crust. In laboratory experiments, the evolution of damage with increasing stress leads to localization, and both slow and fast slips generate damage. The similarities and differences between shallow damage (upper few km) and deep damage (>20 km deep) from microstructures, mineral composition, lithology and geophysical observations are subject to considerable recent studies. This session aims to discuss why and how fault damage zones form and evolve across the entire crust. We encourage multi-disciplinary contributions from geological, geophysical, experimental, and modelling studies of fault damage, including novel techniques to extract information from large data sets.

Confirmed invited speakers
Frans Aben, Univercity College, London
Bjørn Jamtveit, University of Oslo

The abstract submission deadline is July 31, 2019.
