Session Description:
Space geodetic positioning data (particularly GNSS and InSAR) are commonly used to evaluate how plate motion is being taken up by continental deformation and the mechanisms of elastic strain cycles. Such studies often integrate geodetic solutions with geological and geophysical data in computational models. We are inviting studies that utilize geodetic and geologic/geophysical observations to investigate the character of intra-plate and plate boundary deformation zones, interseismic strain accumulation and co- and post-seismic strain release. We seek studies that help to answer many related questions like (but not limited to): What fraction of plate motion is taken up by fault slip during earthquakes and through creep processes? And what fraction becomes part of distributed deformation off of the major faults? How representative are the present-day angular velocities of the geologic plate tectonic motions? To what degree do postseismic transients perturb the nearly constant velocity of the plates?

2. AGU 2016 Session Announcement | Advances in understanding of tremor, slow slip and other slow earthquake phenomena (Session S003: ID #14143)
Session Description:
Slow earthquakes encompass a variety of behaviors including tectonic tremor, very low-frequency earthquakes, and aseismic slow slip events (SSEs). At times, these behaviors are coincident, while at other times they are observed separately. Slow earthquakes may increase stress loading on the seismogenic zone and hold clues to a more thorough understanding of regional seismic cycles. Studies have indicated slow earthquakes to be a potential precursor of megathrust earthquakes, but the necessary linkage remains unclear. Additionally, up-dip transitional zones showing evidence of slow earthquakes can rupture coseismically, producing larger tsunamis and earthquakes than previously expected. This session aims to provide an understanding of slow slip and associated seismic phenomena, and their possible connection to large damaging earthquakes. We welcome abstracts that cover seismological, geodetic, and geological observations, seismicity catalog statistics, laboratory experiments, and theoretical modeling.

3. AGU 2016 Session Announcement | High-resolution topography and dating in active tectonics (Session T011: ID #13198)
Dear SCEC Community,
We invite you to submit abstracts to AGU Tectonophysics Session #T13198:
https://agu.confex.com/agu/fm16/preliminaryview.cgi/Session13198
High-resolution topography and dating in active tectonics
Active tectonics research involves the measurement of spatial and temporal patterns of crustal deformation throughout the earthquake cycle. A better understanding of the complexities with which tectonic strains are accumulated and released requires the combination of investigations that span different spatial and temporal scales. It requires precise information on when, where, and how much strain is accumulated (and released)–and that over multiple time-scales.
The rapidly increasing availability of high-resolution topographic data–derived from lidar surveys or photogrammetric approaches–provides unprecedented opportunities for precise (and quantitative) investigations of surface deformation. Combined with improved Quaternary dating methods, these new geomorphic constraints enable us to quantitatively understand multiple time scales of deformation, from millennial tectonic strain accumulation processes to occurrence and recurrence characteristics of historical earthquakes.
We welcome contributions that apply high resolution topography and/or dating approaches to questions quantifying active tectonics and geomorphic processes.
The invited speakers are Stephen DeLong, USGS, and Takashi Oguchi, University of Tokyo

4. AGU 2016 Session Announcement | Energy partitioning during earthquakes, landslides and other shear failure processes (Session S006: ID #12811)
Dear Colleagues,
We would like to draw your attention to an AGU session entitled “Energy partitioning during earthquakes, landslides and other shear failure processes”. Please consider to submit an abstract by August 3rd, 23:59 EDT.
https://agu.confex.com/agu/fm16/preliminaryview.cgi/Session12811
Session Description:
During shear failure processes, such as earthquakes and landslides, the released potential energy is partitioned into kinetic/radiated seismic energy and energy dissipated by friction and inelastic deformation. Energy partitioning during shear failure is one of the most fundamental but challenging issues that needs to be quantified in order to understand the basic physics of the process. The key controlling parameters for the energy partitioning, such as rupture speed, material strength, stress drop, surface roughness, friction, etc., have been extensively investigated with seismological observations, numerical modeling, structural geology field work, and laboratory experiments of rock mechanics and granular flows at different scales. We welcome submissions from this broad range of disciplines with the intent of establishing what we have observed and understood so far, and to define the key issues to achieve better understanding in the future.

5. AGU 2016 Session Announcement | Reliability of the Green’s function extracted from ambient noise (Session S024: ID #12831)
Dear colleagues,
We would like to draw your attention to our AGU session “Reliability of the Green’s function extracted from ambient noise” (session ID 12831). In this session, we discuss the extraction of reliable information from ambient noise based on cross correlation techniques. All theoretical and methodological approaches are welcome. The detailed session description is attached below.
We are very proud of inviting Francisco Sanchez-Sesma (UNAM) and Loic Viens (University of Tokyo).
Abstracts can be submitted via the AGU Fall Meeting website (https://fallmeeting.agu.org/2016/abstract-submissions/ ). The deadline is 3 August.
Please, feel free to forward that message to anyone who could be interested by this session.
Best regards,
Nori Nakata (Stanford University)
Zack Spica (Stanford University)
Session Description:
Ambient-noise based seismological techniques have been used for understanding the 3D/4D Earth’s properties such as structure, stiffness, and attenuation in various scales. The key for the precise estimation of these parameters is the accuracy of the Green’s function extracted, which relies on, for example, ambient-noise energy distribution, receiver coverage, and appropriate signal processing.
In this session, we focus on theoretical and methodological approaches for extracting more accurate Green’s functions, and their applications. We invite contributions of novel processing and data acquisition (e.g., C3, double beamforming, multi-dimensional deconvolution (MDD), or very dense receiver array) to overcome azimuthal variation of ambient noise energy. Presentations related to amplitudes extraction, higher-mode surface waves, Love waves, or body waves in addition to the phases of the fundamental-mode Rayleigh waves are highly encouraged. We also welcome studies of the usage of multi-component signals for ambient-noise correlation, which can decompose different wave types.
6. AGU 2016 Session Announcement | Operational Earthquake Forecasting: Scientific Advances, Validation and Implementation, Communication and Uptake (Session S022: #13049)
Earthquakes seldom come alone; they often trigger additional earthquakes that exacerbate existing crises or indeed initiate a disaster. The recent M7 April 15, 2016, Kumamoto, Japan earthquake occurred mere days after two earlier M6 temblors, serving as yet another dramatic example of a so-called aftershock that proved to be more damaging than the initial mainshock. This session focuses on recent progress in operational earthquake forecasting (OEF), which involves the generation and timely dissemination of authoritative information about time-dependent seismic hazard, with the purpose of helping communities prepare for earthquakes. We invite contributions spanning the range of challenges facing OEF. Topics may include: scientific advances in physical and statistical modelling of earthquake triggering, clustering and cascading; validation and evaluation of forecast skill; operationalization and implementation in real-time, including data access issues and uncertainties; best practices for communication; and uptake from existing and potential users of operational forecasts.
