From contact at sz4d.org Fri Jul 1 07:32:39 2022 From: contact at sz4d.org (SZ4D Office) Date: Sat Dec 10 20:28:09 2022 Subject: [SZ4D] Reminder: Serve on an SZ4D Committee Message-ID: *SZ4D offers a range of options to get involved in the initiative.* *Deadline to volunteer is today.** Join now !* One of the most important ways to participate in the SZ4D initiative ( www.sz4d.org) is to join one of our oversight committees. These committees will allow you to represent your community?s priorities as the SZ4D begins its implementation phase. They will be instrumental in helping to design the overall structure of the SZ4D, the types of instrument arrays that will be necessary to answer the SZ4D science questions, and to build capacity and equity in the initiative. If you would like to get involved, fill out this form , indicating your interest in serving. If you have anyone else that you?d like to recommend for committee membership, we?d like to know that as well. This information will be compiled by a special committee, called the Committee on Committees, which will develop a slate of potential candidates for each of the oversight committees described below. The Committee on Committee?s membership does not include any members serving on the new committees, so they can dedicate their efforts to ensuring equity, inclusion, and a diversity of viewpoints are built into the SZ4D. This slate will initially be approved by the SZ4D Research Coordination Network steering committee ? this approval process will be transferred to the SZ4D Center Steering Committee (described below) once the RCN Steering Committee is replaced by the new, transitional committees. The SZ4D RCN has developed a set of transitional committees meant to promote involvement in the SZ4D as the program gets going. Each committee has a different level of responsibility, which corresponds to the commitment associated with it. *Disciplinary & Integrative Working Groups* If you are interested in participating in the effort, but your time and capacity are limited, you might consider volunteering for one of our *disciplinary working groups* or *integrative groups*. The disciplinary groups will provide scientific input for each of the three major disciplines represented by the SZ4D (Land- and Seascapes , Magmatic Drivers of Eruption , and Faulting and Earthquake Cycles ), while the integrative groups will focus on Building Equity and Capacity in the Geosciences and the Modeling Collaboratory for Subduction efforts. *Collective Impact Committee* The working & integrative groups will provide input to the *Collective Impact Committee*, which provides cross-cutting, scientific input and prioritization to the SZ4D effort. If you are interested and able to dedicate effort to the SZ4D effort, this might be an exciting opportunity to help guide the SZ4D in a way that balances the needs of all of its disciplinary and cross-cutting priorities. *Operations Planning Committee* The *Operations Planning Committee* will be responsible for the development and coordination of the actual SZ4D deployments. So, if you?re deeply interested in instrumentation or field campaigns, this committee is for you. *Center Steering Committee* Finally, if you?re ?all-in? on SZ4D and want to participate in the day-to-day work of the project, we could use your help on the *Center Steering Committee*. This committee is responsible for moving the project forward based on the directives of the Collective Impact Committee, and the deployment specifications provided by the Operations Planning Committee. This would allow you to be deeply involved in the SZ4D, and to be able to work on behalf of your community to bring the SZ4D to life.

No earthquakes >M5 have been observed on the subduction interface since modern seismic recording began, but there are a variety of fault slip behaviors happening on the interface, including creep, locking, and transient slow slip events (SSEs). Understanding the physical processes of deformation and quantifying the degree of plate interface coupling between the coast and the trench is a critical to assessing the interseismic slip deficit on the megathrust, which directly controls the seismic hazard of the Cascadia subduction zone. Given Cascadia?s low earthquake rate, geodetic observations of interseismic deformation from new seafloor sensors, conventional onshore sensors, and remote sensing provide our best path forward for assessing earthquake hazard in Cascadia. Our ability to estimate ongoing deformation in Cascadia has been limited because conventional geodetic observations (such as GNSS and InSAR) could only be made onshore. However, new offshore geodetic datasets offer untapped resources for understanding deformation. University partners and the USGS are constructing seafloor geodetic (GNSS-A) monuments. (Seven exist with another seven proposed for installation next year.) The 2011-2015 Cascadia Initiative collected seafloor pressure records at 60 ocean-bottom seismometer locations. Finally, two cabled networks continue to provide long-duration time series of seafloor pressure: at 18 NEPTUNE observatory stations operated by Ocean Networks Canada since ~2010 and at one NSF-funded Ocean Observatories Initiative station since 2014. Onshore geodetic data sources include NOTA strainmeters and continuous GNSS stations, and Central Washington University?s Pacific Northwest Geodetic Array (PANGA). A wealth of other complementary data (e.g., satellite sea surface height and temperature, bathymetric, and seismic imagery data) also exist. Use of data from other regions also is encouraged. We seek an individual with background and interest in geodesy or seismology to pursue research on aseismic deformation in Cascadia. In addition to the frontier nature of the data types available in the Cascadia region and the novelty of fusing seafloor, land- and space-based geodetic observations, advances in modeling techniques should be utilized to expand our understanding of subduction zone deformation processes. These include information theory approaches, probabilistic inference, machine learning-based signal extraction, error modeling, uncertainty quantification, and new high-performance computing frameworks. Interested applicants are strongly encouraged to contact the Research Advisor(s) early in the application process to discuss project ideas.

In many subduction zones slip downdip of these megathrust earthquakes transitions to slow, but unsteady motion on the plate interface. These slow slip events incrementally increase stress on the locked portion of the fault, with the possibility of triggering or evolving into a megathrust earthquake. However, the causal relation and transition between these fast and slow slip modes are not well understood. Slow slip is often accompanied by unusual seismic signals that exhibit longer durations and lower frequencies than typical earthquakes. Tectonic tremor, low-frequency earthquakes (LFE), and very low frequency earthquakes (VLFE) have been documented in subduction zones worldwide. These signals mark the occurrence of slow slip. Research focused on the transition in behavior from the updip edge of observed tremor and slow slip into the zone where an eventual megathrust rupture is expected to occur provides a key opportunity to improve understanding of the interactions between slow and fast slip subduction zones. Indeed, recent studies have provided tantalizing new evidence in Cascadia about slip behavior within this transition zone; e.g., identification of large VLFEs using far-field seismic and local strain data. The focus of this Mendenhall Research Opportunity is to investigate the transition from fast to slow slip. We seek a postdoctoral Fellow who has expertise in subduction zones, slow slip and slow slip seismicity. We anticipate this project will center around analysis of seismic and strainmeter data, but inclusion of other data is encouraged. The Fellow?s work will provide a better understanding of the role of slow slip in the earthquake cycle, the transition from fast to slow slip along the fault interface, the properties of the interface that may control slip modes, the stationarity of slip modes, and the spatial gap between the locked and tremor-generating portions of the fault. We encourage candidates to propose novel approaches for characterizing slip at the transition. Proposals are encouraged to focus on the Cascadia and/or Alaska subduction zones, and could include leveraging existing tremor, LFE and VLFE catalogs; new seismic imaging data; interrogating onshore and offshore seismic and pressure data; combining GNSS or strain data with seismic observations and other relevant approaches.

NH019 - Performance, Progress, and Promotion of Earthquake Early Warning Worldwide Conveners: Elizabeth S Cochran (U.S. Geological Survey), Danielle Sumy (Incorporated Research Institutions for Seismology), Jessie K Saunders (Caltech), Sara McBride (U.S. Geological Survey), Amy L Williamson (UC Berkeley) In 1993, Mexico initiated the first earthquake early warning (EEW) system with public alerting. The United States, Japan, Taiwan, India, Romania, Israel, Italy, New Zealand, and others are now in various stages of development and deployment of EEW systems. EEW pushes the frontiers of science and engineering yet is an inherently social and humanitarian effort to protect people and key infrastructure from the effects of strong ground shaking. EEW alerts must be issued quickly to provide actionable warning; thus, we must find novel solutions to detect, characterize, and communicate expected shaking based on limited observations. This session explores innovations in data acquisition and telemetry; geophysical algorithm developments that determine alert regions; and education and messaging tailored to mitigate risk and meet societal needs. We welcome abstracts on the intersection of earthquake science, engineering, technology, education, and social science that improve the reliability and utility of EEW systems. V020 - Volcano Seismology and Acoustics: Recent Advances in Understanding Volcanic Processes Conveners: Oliver D Lamb (University of North Carolina at Chapel Hill), Helen A Janiszewski (University of Hawaii at Manoa), Jacqueline Caplan-Auerbach (Western Washington University), Josh A Crozier (USGS California Volcano Observatory) Hazardous phenomena at volcanoes include ash plumes, gas emissions, explosions, pyroclastic density currents, lava flows, lahars, and mass wasting. All of these processes produce seismic and acoustic signals that can provide key real-time information for assessing hazardous surface and atmospheric activity. We can also gain insights into the structure and activity state of volcanoes by identifying and tracking the movement of subsurface magma and hydrothermal fluids using seismicity and seismic imaging techniques. Recent advances in seismo-acoustic instrumentation, deployment techniques, and data analysis have promoted more precise characterization and quantification of the physical mechanisms leading to and accompanying volcanic phenomena. Thus, volcano seismology and acoustics remains a rapidly developing area of research. We welcome submissions that present new seismic, infrasound, and hydroacoustic observations, interpretations, models, instrumentation, or techniques that improve our understanding of volcanic processes and assist future monitoring efforts. Invited speakers are Ettore Biondi from Caltech and Julia Gestrich from the University of Alaska Fairbanks. T017 - Subduction Top to Bottom (ST2B) ? Origin and Evolution of Magmatic Arcs Conveners: Gray E Bebout (Lehigh University), David William Scholl (University of Alaska Fairbanks), Robert J Stern (University of Texas at Dallas), Ikuko Wada (University of Minnesota Twin Cities) To the SZ4D community, This is an advertisement for a session on the Origin and Evolution of Magmatic Arcs to be run at the Fall 2022 AGU meeting in Chicago (Dec. 12-16). This session is a part of the Subduction Top to Bottom venture, the latter in which we stress multidisciplinary approaches to study of subduction processes. This pursuit recently resulted in a Themed Issue with 74 papers at the journal GEOSPHERE (all Open Access): https://pubs.geoscienceworld.org/geosphere/pages/st2b2 We seek multidisciplinary perspectives on the processes leading to the formation and evolution of magmatic arcs (field/geological, geophysical, geochemical, experimental, theoretical). We encourage you to consider participating in this session - the abstract deadline is August 3. Session description: The ST2B pursuit highlights and fosters multidisciplinary research on subduction margins, gathering scientists representing the full array of approaches and perspectives. In this session, we focus attention on factors and processes leading to arc magmatism, both modern and ancient, aimed at refining our understanding of primary forcing factors (including structural controls) for the production and positioning of arcs and exploring the great diversity in arc systems. We hope to sponsor discussion of all aspects of arc evolution, including but not limited to the impact of forearc dynamics, the nature of the subduction interface, slab devolatilization and melting, the physical and chemical characteristics of slab/sediment-derived ?fluids,? mantle wedge thermal, rheological, and chemical evolution, the role of diapirs, and whole-margin volatiles cycling. We hope to stimulate discussion among geodynamic modelers, geophysicists, geochemists, and experimentalists, and to engage those investigating ancient arc magmatism and Earth?s long-term history of subduction. Invited speakers: Christy Till (Arizona State University) Leif Karlstrom (University of Oregon) GC076 - Science and Technology towards Achieving Surface Topography and Vegetation Structure Measurements Conveners: Andrea Donnellan (Jet Propulsion Laboratory, California Institute of Technology Convener), Craig L Glennie (University of Houston) The 2017 Decadal Survey for Earth Science and Applications from Space identified the Surface Topography and Vegetation (STV) as a targeted observable for maturation. STV will acquire high-resolution, global height measurements, including bare surface land topography, ice topography, vegetation structure, and shallow water bathymetry. These measurements will serve a broad range of science and applications objectives that span solid earth, cryosphere, biosphere and hydrosphere disciplines. A common set of measurements could meet many of the community needs serving a wide array of disciplines. STV objectives would be best met by new observing strategies that employ flexible multi-source and sensor measurements from a variety of orbital and sub-orbital assets. Science and application objectives focusing on Solid Earth, Vegetation Structure, Cryosphere, Hydrology, and Coastal Processes would be best met by new, 3-dimensional observations from lidar, radar, and stereo photogrammetry. Simulations, experiments, data analysis and technology development in interferometric SAR, lidar and stereo photogrammetry approaches, platform options and system architectures will all mature STV toward an observing system. This session invites submissions on science and technology maturation activities for STV. The complete STV report from the first incubation study team can be found at https://science.nasa.gov/earth-science/decadal-stv/ T002 - Comparative investigations of Slow-to-Fast Earthquakes: Observations, Experiments, and Numerical Modeling Conveners: Yoshihiro Ito (Disaster Prevention Research Institute, Kyoto University, Laura M Wallace (University of Texas at Austin), Matt Ikari (MARUM, University of Bremen), Victor M Cruz-Atienza (Universidad Nacional Aut?noma de M?xico) Both slow and fast ruptures on faults are commonly observed in a variety of tectonic environments worldwide. This session aims to identify the factors that control such slow and fast ruptures using data obtained from seismic and geodetic observations, geological fieldwork, laboratory experiments, and numerical modeling. We welcome multidisciplinary contributions that undertake comparisons among different subduction margins and other plate boundary environments to reveal the physical processes that control slow vs. fast earthquakes, and the linkages between these phenomena. By distinguishing both global and regional factors controlling the slow and fast rupture processes, an ultimate goal is to develop a conceptual model explaining their occurrence. In addition to investigations focused on fault slip, we also welcome contributions revealing slow vs. fast deformation processes in landslide and glacial environments, as these may provide important analogues to increase understanding. T011 - Multiscale Crustal Deformation in Subduction Zones and the Megathrust Earthquake Cycle: Progress from Observations and Models Conveners: Haipeng Luo (McGill University), Matthew W Herman (California State University Bakersfield), Aron J Meltzner (Nanyang Technological University), Donna J Shillington (Northern Arizona University) The timescales of deformation in subduction zones span seconds to millions of years. Associated with these timescales is a spectrum of deformation behavior, from elastic to permanent brittle or ductile. The patterns of slip on the plate boundary throughout the megathrust earthquake cycle and the rheology of crust and mantle are central to this deformation. There is also a complex relationship between short- and long-term deformation processes. Observations from modern seismology, geodesy, paleogeodesy, geophysics, and geology along with advances in modeling capabilities are revealing the details of these processes. As a result, there is much new understanding of the crustal deformation at subduction margins across time and space in association with megathrust coupling/slip and subduction zone rheology along with other tectonic and non-tectonic processes. We welcome submissions on all aspects of crustal deformation to explore the geodynamic processes governing earthquake cycles and the long-term evolution of the subduction margins. -------------- next part -------------- An HTML attachment was scrubbed...

Structure, Mechanics, and Hazards of Geometrically Complex Fault Systems Conveners: James Biemiller, Roland Burgmann, Alice-Agnes Gabriel, Alba M Rodriguez Padilla Dear Colleagues, Please consider submitting an abstract to our AGU session on multi-fault systems: Across many tectonic settings, major active fault systems commonly consist of multiple intersecting or neighboring faults. High-resolution observations from recent large earthquakes show that these events often rupture multiple fault segments and generate significant off-fault damage. Over a wide range of timescales, details of the mechanical interactions between segments in complex fault systems remain challenging to untangle. Nonetheless, these interactions appear to influence the seismic and tsunami hazards resulting from complex earthquake ruptures. This session will focus on new observations and models that illuminate how complex fault systems form and deform over geologic to coseismic timescales, and how complex faulting affects natural hazards for nearby communities. Submissions are encouraged from a broad range of disciplines including geology, geomorphology, seismology, geodesy, rock mechanics, and geodynamics, among others. H029 - Applied Terrestrial Gravimetry: Monitoring and Modelling Environmental Processes Conveners: Marvin Reich (GFZ), Jeff Kennedy (USGS), Jean Lautier-Gaud (Muquans) and Andreas G?ntner (GFZ) Dear community, I wanted to draw your attention to our repeated AGU session on "Applied Terrestrial Gravimetry: Monitoring and Modelling Environmental Processes". As we know you work in this very field, we would strongly encourage you to contribute to this session. It would be an honor! Terrestrial gravimetry has gained significant importance throughout the last decade for monitoring hydrological and other environmental processes. Nevertheless, the complete workflow from instrumental operation to interpretation of processed data is complex and requires broad and detailed inter-disciplinary knowledge. The hydrological signal component of gravity is a key example: while hydrologists want to use it for hydrological process understanding and modelling, others need to remove it as noise before further interpretation (e.g., in the fields of volcanology, geodesy, reservoir monitoring in geothermal energy or carbon storage). This session aims at addressing all applied aspects of terrestrial gravimetry, including but not limited to: innovative gravimeter technologies, instrumental setups, monitoring strategies, data processing, signal separation and environmental interpretation. We want to encourage discussions from different user perspectives to sensitize each other on respective challenges and to ultimately foster trans-disciplinary cooperation towards advanced applications. Please feel free to forward this announcement to anyone who you think would fit to this topic. Best regards, Marvin Reich and co-conveners Jeff Kennedy (USGS), Jean Lautier-Gaud (Muquans) and Andreas G?ntner (GFZ) G008 - Plate Motion, Continental Deformation, and Interseismic Strain Accumulation Conveners: Donald F Argus (NASA Jet Propulsion Laboratory), Jeffrey Todd Freymueller (Michigan State University), D. Sarah Stamps (Virginia Polytechnic Institute and State University), Rui Manuel Silva Fernandes (University of Beira Interior) We invite submissions to our AGU session, Plate Motion, Continental Deformation, and Interseismic Strain Accumulation. This session is always stimulating and exciting, and we expect the same this coming year! Please submit your abstract and present your work. We seek studies examining the take up of plate motion in deforming zones and the buildup and release of elastic strain along major faults and in subduction zones using space geodetic measurements, geologic observations, and geophysical data such as seismicity, marine magnetic anomalies, and transform fault azimuths. How can GPS and InSAR be integrated to determine deformation in plate boundary zones? To what extent can observed elastic strain buildup and past earthquakes be used to infer the likelihood of future earthquakes? Are fault slip rates from paleoseismology identical to those from geodetic data? 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 fast are mountains currently rising? To what degree do postseismic transients alter the nearly constant velocity of the plates, and how can postseismic transients influence the definition of Earth's reference frame? -------------- next part -------------- An HTML attachment was scrubbed...
