----------------------------------------------------------------------------------------------------------------------------------------------

Dear Colleagues,

We would like to encourage submissions to this AGU special session:

T007: Continental Rifts and Passive Margins: Geology, Geophysics, Geodynamics (Session ID#: 22111)
https://agu.confex.com/agu/fm17/preliminaryview.cgi/Session22111

Session Description:
This session invites contributions on rifts and rifted margins that integrate new data sets, approaches or viewpoints. Studies can range from the outcrop to the basin or lithospheric plate scale, and include global examples. Innovative concepts and techniques based on field geology, seismology, geodesy, marine geophysics, plate reconstructions, geochemistry, sedimentology, or modeling are encouraged. Topics may include but are not limited to fault dynamics, shear zones, tectono-magmatic and sedimentary processes, impact of volatiles, the continent-ocean transition, influence of mantle dynamics and surface processes, and the role of tectonic inheritance. We particularly encourage submissions that explore along-strike structural and magmatic variations in rifts and passive margins linked to 3D modeling studies. Emphasis will be given to presentations conveying an integrated picture by bridging spatial or temporal scales, or by combining results from active rifts, failed rift arms, passive margins or fossil rifted margins exposed in mountain belts.

Conveners:
Sascha Brune, GFZ, Potsdam
W Roger Buck, Columbia University
Patricia Persaud, Louisiana State University
Gianreto Manatschal, University of Strasbourg

We hope to see you in New Orleans in December! As a reminder, the abstract submission deadline is August 2.

2. T043: The Influence of Fault Zone Structure on Plate Boundary Tectonics and Earthquakes (Session ID#: 26243)
--------------------------------------------------------------------------------------------------------------------------------------------------------

We invite you to consider submitting an abstract to the 2017 AGU Fall Meeting:

T043: The Influence of Fault Zone Structure on Plate Boundary Tectonics and Earthquakes

Session ID#: 26243
Session Description: This session seeks to highlight studies of fault zone properties in relation to transient slip, triggering, and rupture propagation direction across plate boundaries. Probabilistic-hazard source models may overestimate expected earthquakes in California. Paleoseismic and historical data in southern California indicate a 160 year long hiatus in great earthquakes. Factors affecting hazard model performance can include insufficient characterization of transient slip, slip triggering, and fault zone damage properties. These factors may arise in part because the crust is not purely elastic, and compliant material can serve to relieve stress aseismically. Differences in seismic velocities within the crust and fault geometry can control rupture propagation direction and whether earthquakes jump from one segment to another, cascading into larger events. This session encourages results based on geodetic, geologic, and seismic data that illuminate spatial and temporal patterns connecting fault zones with plate boundary deformation.

Co-Organized with: Tectonophysics, Geodesy, Nonlinear Geophysics, Natural Hazards, and Seismology

3. G014: Plate Motion, Continental Deformation, and Interseismic Strain Accumulation (Session ID#: 22151)
-----------------------------------------------------------------------------------------------------------------------------------------------

Dear Colleagues,

We would like to draw your attention to the 2017 AGU Fall Meeting session “G014. Plate Motion, Continental Deformation, and Interseismic Strain Accumulation”. We hope to bring together contributions from multiple disciplines to highlight recent advances in this field. Please see below for details.

Submission deadline: Wednesday, 2nd August 23:59 EDT.

Please submit your abstracts to: https://agu.confex.com/agu/fm17/g/papers/index.cgi?sessionid=22151

Conveners:
Donald F Argus, JPL
Jeffrey Todd Freymueller, University of Alaska Fairbanks
Rui Manuel Silva Fernandes, Universidade da Beira Interior, SEGAL
D Sarah Stamps, Virginia Polytechnic Institute and State University

Session Description:
Space geodetic data, geophysical and geologic observations and models constrain how plate motion is being taken up by continental deformation and how elastic strain accumulates between earthquakes. We invite geodetic, (e.g., GNSS, InSAR, VLBI, etc) and geologic and geophysical studies (e.g., fault slip rates, seismicity, and marine magnetic anomalies) that characterize stable plate interiors, plate boundary zone deformation and interseismic strain accumulation. New efforts using modern cyberinfrastructure and open software are particularly welcome. Can elastic strain buildup be readily related to future great earthquakes? What fraction of plate motion is taken up by fault slip during earthquakes, and what fraction becomes part of distributed deformation off the major faults? How does fault slip inferred from paleoseismology add up to present-day plate motion? How fast are mountains currently rising? To what degree do postseismic transients perturb the nearly constant velocity of the plates and influence the definition of Earth's reference frame?

S018: Earthquake rupture revealed by kinematic source imaging
Session ID#: 24872
Session Description:

Large earthquakes exhibit great complexities. These earthquakes can involve multiple fault segments or multiple faults, and trigger large nearby aftershocks instantaneously. The complexity of large earthquakes stimulates developments of novel methods to map rupture evolution with multiple geophysical data sets. Combinations of datasets, such as seismic, geodetic and tsunami observations, have greatly improved the resolution of kinematic earthquake models and our understanding of earthquake rupture processes, but physics-based statistical approaches are needed to efficiently combine disparate data sets. Besides explaining multiple geophysical observations, quantifying source model uncertainties is equally important to identify robust features of the inferred rupture processes. We invite contributions related to kinematic source imaging, improved uncertainty quantification, and the combination of multiple datasets. In particular, we solicit studies that provide unified interpretations of observed earthquake kinematics with dynamic rupture simulations, post- and inter-seismic processes, tectonic setting, and laboratory experiments to reconcile observations over multiple scales.

6. S020: Observing Fault Slip in its Natural Habitat: Field Experiments of Earthquake Physics (Session ID#: 25440)
--------------------------------------------------------------------------------------------------------------------------------------------------------

As the AGU Fall Meeting abstract deadline approaches (Aug. 2nd), please consider submitting (http://fallmeeting.agu.org/2017/abstract-submissions/) an abstract to our session.

S020: Observing Fault Slip in its Natural Habitat: Field Experiments of Earthquake Physics(https://agu.confex.com/agu/fm17/preliminaryview.cgi/Session25440)

Invited Speakers: Yasuo Yabe and Yves Guglielmi

Session Description:
Controlled experiments at the field scale are required to improve our understanding of earthquakes. Scientifically induced seismicity can bridge the gaps between laboratory, theoretical and observational studies on natural systems. Artificially produced earthquakes can provide key information about the forcing mechanisms required to initiate events on natural, pre-stressed faults. The controlled nature of the experiment also provides an opportunity for near-field instrumentation to examine nucleation and the controls on ultimate magnitude posed rupture propagation. We encourage submissions that illuminate earthquake physics utilizing induced seismicity or focus on near-field observables that might be applicable to future controlled field experiments.

7. G006: Geodetic imaging and interpretation of the seismic cycle,” (Session ID# 25150)
--------------------------------------------------------------------------------------------------------------------

Hi all,

We would like to invite those interested to attend and submit abstracts to a session we are running in the Geodesy and Tectonophysics sessions at this year's AGU Fall Meeting, "Geodetic imaging and interpretation of the seismic cycle," session G006 (ID# 25150).

Session Description:
Geodesy’s ability to image earth processes has vastly improved both spatially and temporally in recent decades, making it an essential tool to study the seismic cycle and the ways the earth accommodates tectonic strain. To use geodesy to image these processes in a complex earth, it is essential to 1) correctly separate the contributions made by seismic, aseismic and nontectonic deformation in the data, and then 2) link these observations to fault and bulk processes with a full view of their spatiotemporal complexities. We welcome studies on all aspects of geodetic imaging of the seismic cycle: from improved techniques to detect tectonic signals (e.g. probabilistic, sparsity-promoting, etc.) and separate them from other deformation sources (e.g. hydrological, thermoelastic, anthropogenic), to the modeling and interpretation of the deformation mechanisms that produce them (e.g. coseismic slip, afterslip, viscoelastic relaxation, poroelastic rebound, slow slip events, long-term creep, gravity-driven postseismic deformation).

Conveners:
Christopher Rollins, Caltech
Adriano Gualandi, Caltech
Mong-Han Huang, NASA Jet Propulsion Laboratory
Jessica R. Murray, USGS Menlo Park

Feel free to send any questions or comments to me at jcrollin@caltech.edu or to any of the co-conveners, and we hope to see you there! As a reminder, the abstract submission deadline is 11:59 PM Eastern Standard Time on August 2.

Thanks,
Chris
