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. T030 Reconciling geologic and geodetic fault studies: do they even need to be reconciled? (Session ID#: 23156)
--------------------------------------------------------------------------------------------------------------------------------------------------------

Description:

Quantifying crustal deformation across geodetic and geomorphic timescales may not always produce consistent results, leading to questions about which approach may be most appropriate for interpreting fault activity and seismic hazard. Geodetic techniques such as Global Navigation Satellite Systems (GNSS) and Interferometric Synthetic Aperture Radar (InSAR), record active accumulation of tectonic strain across seismogenic fault zones on decadal timescales. Paleoseismology and tectonic geomorphology are capable of probing deeper in time, but must average over several earthquake cycles to estimate fault slip rates, and often cannot resolve slip heterogeneity along fault strike and depth. We encourage submissions exploring strengths and weaknesses of geologic and/or geodetic approaches to understanding active fault systems, and novel approaches for reconciling geologic and geodetic information: Under what conditions might we expect geologic and geodetic slip rates to agree or disagree? What do geologic and/or geodetic measurements reveal about slip partitioning throughout the earthquake cycle?

2. (GSA) T217: Tectonics 5: Synergies between Meeting Societal Needs and Advancing Interdisciplinary Research in Tectonics and Structural Geology (Session ID#: 43268) [GSA]
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Description:

This session focuses on fundamental research in structural geology, tectonics, and related fields that addresses topics of societal relevance, from resources to hazards and that leverage field, laboratory, experimental, numerical, and theoretical approaches.

Geoscience plays a pivotal role in addressing fundamental research questions that are of immediate concern to society and many of these questions are addressed within the interdisciplinary fields of structural geology and tectonics, and related fields such as geochronology, geomorphology, paleoseismology, seismology, and geochemistry. Such research aligned with meeting the needs of society can break down presumed divisions between theoretical and applied science. We encourage studies that leverage the necessary data, observations, technology and models that meet the needs of society, from resources to hazards. Research themes for this session may include, but are not limited to, the structural control of mass and heat transport in the lithosphere including the migration of water and hydrocarbons, the safe long-term storage of nuclear waste and anthropogenic CO2, the relationship between tectonic processes and hazards along plate boundaries and plate interiors, interactions between tectonic processes, anthropogenic climate change, and landform evolution, and structure and tectonics research that benefits from opportunities linked to its societal relevance. What are the pathways to modeling hazard and ultimately risk in a region? What data and technology are necessary to better characterize and manage resources? What existing data, technologies, and models can we leverage for this research? In the 21st century, what are the problems of high societal relevance that are likely to yield new data, techniques, or technologies that will promote fundamental earth science advances? We encourage submissions from interdisciplinary structural and tectonic research that address these and similar questions incorporating field, laboratory, experimental, numerical, or theoretical approaches.

3. G015: Recent Advances in SAR and InSAR Processing, Analysis, and Cloud Computing (Session ID#: 26762)
-----------------------------------------------------------------------------------------------------------------------------------------------------

Hello all (apologies in advance for any cross-postings),

The AGU abstract submission deadline is rapidly approaching, and if you exploit SAR or InSAR data in your research (as a participant in the Community Geodetic Model project, say), do consider submitting to this wonderfully broad and welcoming session!

G015: Recent Advances in SAR and InSAR Processing, Analysis, and Cloud Computing (Session ID#: 26762)

Session description:
We are entering a golden age of civilian SAR remote sensing with ~10 satellites in orbit and a fleet of new SAR satellites (including NISAR) to be launched by 2020. This wealth of data provides the geoscience community with enormous opportunities but also significant technical and logistical challenges. This session, co-sponsored by WInSAR and the Alaska Satellite Facility, aims to prepare the ground for addressing these challenges.

We solicit contributions showcasing recent developments in SAR in the following three areas: (1) Recent developments in data processing techniques that take full advantage of the densely sampled time-series information provided by modern SAR sensors, including both InSAR and SAR amplitude time-series methods. (2) Recent advances in big data and cloud-based processing techniques applied to SAR and InSAR, and development and distribution of value-added products. (3) Submissions that apply SAR and InSAR data to analyzing Earth science problems and/or the monitoring of geohazards.

4. AT008: Creep on Faults: Aseismic Slip Throughout the Earthquake Cycle (Session ID: #24898)
---------------------------------------------------------------------------------------------------------------------------------

Dear colleagues,

Please consider submitting an abstract to the AGU Fall Meeting session
T008: Creep on Faults: Aseismic Slip Throughout the Earthquake Cycle (session ID#24898)
https://agu.confex.com/agu/fm17/t/papers/index.cgi?sessionid=24898

Session Description:
https://agu.confex.com/agu/fm17/preliminaryview.cgi/Session24898
Aseismic slip is a significant mode of moment release on many faults, making spatiotemporal variations in creep an important area of research for understanding fault slip. The many flavors of fault creep include, but are not limited to: interseismic creep, afterslip, and triggered or spontaneous slow slip. Observational, experimental, and modeling studies of creeping fault behavior have recently shed light on the richness of aseismic slip processes in nature, and have revealed that faults display many combinations of seismic and aseismic moment release at different phases of the earthquake cycle. However, much remains to be understood about the frictional and other physical properties responsible for this behavior, and to what extent they are stable over time. In this session, we invite all contributions to the study of fault creep from the interseismic to postseismic phases of the earthquake cycle, including observational, laboratory and modeling investigations.
