Date: 12/05/2014

Dear SCEC Community, 

We are continuing to receive multiple requests for sending announcements. Therefore, we have again compounded these requests below. 


SCEC Information


Esteemed Colleagues

We would like to alert you the following two Special Sessions at the 2015 General Assembly of the
European Geophysical Union (EGU), to be held in Vienna April 12-17, 2015.
Abstract deadline for EGU abstract is 07. January, 2015.

Earthquake source processes  - Imaging methods, physical rupture models and scaling

Advances in physics-based forward modeling, source imaging methods, scaling relations for static and dynamic parameters of earthquakes, as well as laboratory experiments help understanding the dynamic processes occurring during seismic ruptures,
but also point to challenging scientific questions still to be tackled:

For instance, what are the first-order physical processes that are relevant, at a given spatio-temporal scale, to control the macroscopic evolution of a dynamic rupture and to affect the resulting ground motion characteristics? Is the physics of fault rupture the same for large and small earthquakes? How can earthquake hazard assessment account for source effects? Which aspects of the source rupture process need to be considered to further investigate local tsunami generation, triggering phenomena, induced seismicity and earthquake cycles?
Earthquake sources are imaged using a variety of seismic data and surface deformation measurements, such as GPS and InSAR, to learn about characteristics of active faults and fault systems. Since each data set has its strength and limitations in imaging specific source properties, a common approach is to combine different data sets into a single inversion. But how robust are these source models? And what are the resulting uncertainties?
Because of the abundance of small events, understanding whether earthquakes are self-similar down to very small ruptures is of practical importance for estimating hazard for natural earthquakes. Studies of earthquake scaling relations involve analysis of the Gutenberg-Richter distribution, seismic moment tensor (e.g. existence of non-DC focal mechanisms) as well as comparisons of static and dynamic source parameters such as stress drop and apparent stress. In spite of increased station coverage in recent years, observations of parameter scaling relationships vary widely.

This session aims at further understanding of source processes and earthquake scaling relationships over a wide range of magnitudes. It discusses advances in numerical and theoretical forward modeling of dynamic earthquake sources. It investigates whether variations in parameter scaling are regionally dependent. It explores whether observed differences in scaling relations are real, and if so, what physical mechanisms might account for such differences. This session is also dedicated to studies that aim at advancing earthquake source imaging techniques to obtain more robust rupture models that are desired to provide a better basis for interpretation of earthquakes with respect to the causative faults and the tectonic systems.
Within this frame our session provides a forum to discuss case studies on recent significant earthquakes, such as the 2009 L'Aquila, the 2010 Chile and Haiti, the 2011 Tohoku-oki and the 2010-2011 New Zealand earthquakes.
Earthquake ground-motion - Source, site and path effects

Ground motion estimation for future earthquakes is one of the most challenging problems in seismology and earthquake engineering. This topic includes source and propagation-dominated ground motion phenomena (including energy channeling, rupture directivity, supershear), complexity in Earth structure (Regional Ground Motion Prediction Equations), nonlinearity, and site effects (basin effects, liquefaction, triggering of landslides, and topographic effects). The quantitative and reliable assessment of those phenomena is required for potential future events in a specific zone, for seismic hazard and seismic risk mitigation. This topic brings together earthquake seismologists and engineers.


Esteemed Colleagues

We would like to draw your attention to the following Special Session at the 2015 Annual Meeting of the Seismological
Society of America (SSA), held in Pasadena April 21-13, 2015. Note that the abstract deadline is January 9, 2015.
See http://www.seismosoc.org/meetings/2015/ for more details.

We encourage all scientists interested in earthquake-source modeling to consider submitting an abstract to this session.
The session will cover topics ranging from innovative source-inversion approaches, and related uncertainty quantification ,
all the way to advanced testing methods for and subsequent use of finite-fault rupture models.

Advances in Earthquake Source Inversion
Earthquake source inversion and high-frequency rupture imaging provide time-dependent information on earthquake rupture processes, but a synoptic view of the origin and impact of the resulting uncertainties on the estimated source parameters has not been fully developed. Furthermore, the optimal integration of various datasets, and the combination of source inversion and source imaging, to derive a complete understanding of the kinematic rupture evolution in space and time, still pose many open questions. In this context, reliable near-real-time finite-fault parameter estimation are needed, as well as high-fidelity rupture-history inversions. This session aims at highlighting recent advances and comparative studies in finite-fault earthquake source inversion, including the development of innovative inversion and imaging methods and the rigorous estimation of model uncertainties. We also invite contributions that integrate observational earthquake seismology with earthquake physics and tectonics, with potential applications in ground motion prediction and early warning studies, to motivate new developments in source characterization, to define new metrics for source inversion validation, and to help build more realistic dynamic models of the earthquake rupture process. In addition, we welcome contributions that highlight developments towards "as-automatic-as- possible" finite-fault inversion, as such procedures will greatly facilitate the validation process of source inversions

Tenure-Track Faculty Position in Solid Earth Geosciences

The Department of Geosciences at The Pennsylvania State University invites applications for a tenure-track faculty position in Solid Earth Geosciences at the rank of Assistant Professor. We seek a colleague who creatively uses theoretical, observational, or experimental approaches to address fundamental problems related to the geochemistry or geophysics of the solid Earth and/or other planets. Successful applicants will be expected to contribute to a dynamic and diverse research and teaching community in the Department and College through the development of a vigorous, internationally recognized and externally funded research program, and through teaching courses in their discipline at the undergraduate and graduate levels. 

The Department of Geosciences is part of the College of Earth and Mineral Sciences, and houses highly active research programs spanning a broad spectrum of Earth Sciences disciplines, including geochemistry, geophysics and geodynamics, and environmental and climate sciences (further information is available at: http://www.geosc.psu.edu). The Department and College are also home to several research centers and programs that focus on Earth and planetary processes, including: AfricaArray; the Center for Geomechanics, Geofluids, and Geohazards; the Susquehanna Shale Hills Critical Zone Observatory; the Penn State Astrobiology Research Center; the Earth System Science Center; and the Penn State Ice and Climate Research Center. 

Applicants must have a Ph.D. in geosciences or a related field at the time of appointment. Candidates should upload a cover letter, a complete curriculum vita, statements of research and teaching interests, and contact information for four references. Please submit these items electronically to job #54781 at https://app2.ohr.psu.edu/Jobs/External/EVMS2_External/currentap1.cfm#54781. Appointment may begin as early as July 1, 2015. Review of applications will begin immediately and continue until the position is filled. For further information or questions, please contact Demian Saffer, chair of the search committee, at dms45@psu.edu.
