1. T047: Transform Plate Boundaries: Mechanics and Hazards (Session ID#: 26428)
-----------------------------------------------------------------------------------------------------------------

Dear Colleagues,

We would like to encourage submissions to the following AGU session:

T047: Transform Plate Boundaries: Mechanics and Hazards (Session ID#: 26428)
https://agu.confex.com/agu/fm17/preliminaryview.cgi/Session26428

Session Description:
Transform plate boundaries offer a window into the mechanical
deformation of lithosphere absent of external mantle processes (corner
flow, upwelling). Continental transforms also present significant
hazards due to their proximity to population centers. A variety of
deformation styles occur at transform plate boundaries, particularly
at fault stepovers, endpoints, and in oblique zones. Recent ruptures
of transform faults including the Kekerengu Fault of New Zealand and
the Queen Charlotte Fault of western North America highlight the need
for improved understanding of the mechanics and deformation processes
associated with transform systems. We seek contributions highlighting
new results from the recent Kaikoura earthquake and studies of the
Queen Charlotte Fault, the San Andreas Fault, the North Anatolian
Fault, and the Alpine Fault. We emphasize the importance of multi- and
cross-disciplinary approaches to study transform systems and welcome
broad contributions, especially research involving earthquake
seismology, paleoseismology, marine geology and geophysics, tectonic
geomorphology, and geodesy.

2. S034 Geophysical Parameter Estimation of the Very Upper Crust: Perspectives from the Field, Lab, and Mind (Session ID#: 24551)
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Dear Colleagues,

Please join us for exciting presentations and enlightening discussion and consider contributing to AGU session S034 Geophysical Parameter Estimation of the Very Upper Crust: Perspectives from the Field, Lab, and Mind. We plan to bring together researchers having distinct perspectives and interests to share common concerns regarding geophysical parameter estimation of the very upper crust.

Session description:
Geophysical parameter estimation of the very upper crust plays a critical role in, for example, geologic hazards, construction, archeology, and natural resource assessment and recovery. Methods of characterization and estimation vary widely from direct and indirect measurement in the field and lab to empirical and theoretical interpolation and extrapolation. In this session, we aim to bring together researchers from various disciplines and settings to present their work on geophysical parameter estimation of the top ~1 kilometer of the crust, which includes, for example, the influence of partial saturation, mixed phases, the water table, unconsolidated sediments, rock fractures, and weathering layers.

Invited Speakers:
Kenneth Stokoe, Georgia Tech
Kristina Keating, Rutgers

Kind regards,
Converners:
Oliver Boyd, USGS, Golden

3. IN041: Looking Ahead to "Universal" Spaceborne InSAR Data Products and Services (Session ID#: 26411)
--------------------------------------------------------------------------------------------------------------------------------------------------

Dear Colleagues,

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

IN041: Looking Ahead to "Universal" Spaceborne InSAR Data Products and Services (Session ID#: 26411)

https://agu.confex.com/agu/fm17/preliminaryview.cgi/Session26411

Session Description:

Each successive spaceborne InSAR system not only leads to more discipline knowledge but also serves a larger community through more useful data products and applications. ESA's Sentinel 1A&B satellites bring unprecedented coverage from freely available wide swath data; NASA's NISAR mission will have similar reach and is now defining just what data products and services best serve science and applications users; e.g., geocoding all products while applying interferometric corrections yields interferograms and time series accessible to a broad spectrum of users, from specialists to those accustomed to more traditional data sets such as LANDSAT. This session solicits papers covering qualities and attributes of products from planned, current and previous InSAR systems, or potential services that offered by agencies or value-added providers, in order to provide a context for and select the best ideas from past and future systems. Also solicited are examples of novel InSAR applications, products, and data flows.

Conveners:
Howard Zebker, Stanford University
Paul Rosen, Caltech Jet Propulsion Laboratory

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

4. T009: Earthquake Recurrence Patterns, and Spatiotemporal Variations of Strain Release Along Faults (Session ID#: 26327)
------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Dear Colleagues,

We would like to encourage submissions to this AGU session:

T009: Earthquake Recurrence Patterns, and Spatiotemporal Variations of Strain Release Along Faults (Session ID#: 26327)

https://agu.confex.com/agu/fm17/preliminaryview.cgi/Session26327

Session Description:

This session aims to discuss the temporal and spatial recurrence patterns of slip along faults accumulated over multiple seismic events. Whether fault slip accumulation follows a ‘characteristic’ pattern with similar magnitude and distribution in successive events, or is more heterogenous (i.e., the ‘variable-slip’ model), has been an open question. The temporal recurrence patterns of events seen in the geologic record also shows a range of behaviors, with some faults exhibiting clustering and others quasi-periodicity. Recent improvements in various geochronologic dating techniques, and measurements of offset geomorphic features from high-resolution topography, can help constrain slip histories and the appropriate recurrence model. Additionally, earthquake simulators and analogue experiments give useful clues into the longer-term behavior of strain release, such as fault evolution and interaction. We encourage submissions which use paleoseismology, geomorphology, earthquake cycle simulations and analogue experiments to explore the patterns and physical mechanisms behind spatiotemporal variations of strain release along faults.

5. PA008: Communicating Science During a Natural Hazard Crisis Session ID#: 27047
-------------------------------------------------------------------------------------------------------------------

Description: A natural hazard crisis requires the communication of
scientific information rapidly, clearly, usefully, and to diverse
audiences. How can scientists, who typically work and communicate at a
more deliberate pace, convey information when time is short and lives
are on the line? What can be done for communities or a country
anxiously seeking more information, forecasts, and, perhaps, a bit of
comfort? This session explores what happens when scientists and
communicators must convey their limited knowledge on emerging
phenomena to the public, policy makers, and an array of stakeholders.
Session themes include: (1) Scientists as media and public
spokespeople; (2) Communication strategies for joint responses by
scientists and communication practitioners; (3) The psychological
function of scientific information in times of crises; (4)
Communication research that focuses on these problems. Our focus is on
geological hazards, such as earthquakes, volcanoes, tsunami and
landslides, but papers on meteorological hazards are also welcome.

Conveners: Michael Blanpied (USGS), Sara McBride (USGS), Lucile Jones
(Caltech), and Kelvin Berryman (GNS Science).
Confirmed invited speakers include Drs. Tim and Deanna Selnow (Univ.
of Central Florida).

6. G013: Near-Surface Structure and the Mechanics of Shallow Fault Slip (Session ID: 22584)
-----------------------------------------------------------------------------------------------------------------------------

We know there are many AGU sessions vying for your attention. But we hope you will consider submitting an abstract to our exciting, cross-disciplinary session co-organized between the Geodesy, Seismology, and Tectonophysics sections:

G013: Near-Surface Structure and the Mechanics of Shallow Fault Slip
https://agu.confex.com/agu/fm17/preliminaryview.cgi/Session22584

Despite application of various geologic and geophysical methods, fault-related deformation in the shallow crust remains poorly understood. For example, geomorphic mapping and paleoseismology recover displacement across discrete fault traces, but cannot resolve slip at depth. Conventional geodetic measurements (e.g., InSAR, GNSS) capture deformation over larger regions and can infer slip at depth, but lack near-field data necessary to constrain shallow slip. Similarly, near-surface fault architecture and rheology are constrained using borehole data, rock mechanics experiments, and seismic tomography, each providing valuable, yet isolated, windows into the physics of shallow faulting. These varied approaches may lead to surprisingly different inferred slip rates, shallow slip deficits, predicted near-field ground motions, and conflicting interpretations of off-fault deformation; affecting our understanding of fault physics and probabilistic seismic hazard analysis. This session welcomes approaches that seek to reconcile these disparate observations and create unified models of the structure and deformation of the shallow crust.
