Multiple Announcements Regarding the USGS Mendenhall Opportunities and a SSA session
Date: 01/07/2015
Dear SCEC Community,
Below are several announcements, one regarding an SSA Session and three concerning the USGS Mendenhall Postdoctoral Research Fellowship Program.
Regards,
SCEC Information
----------------------------------------------------------------------------------------------------------------------------------------------------------------
1.
We would like to announce USGS Mendenhall Postdoctoral Research Opportunity #15-7: 'Analysis of Injection-Induced Seismicity for Improved Hazard Mitigation'. Through this Mendenhall Opportunity, the postdoctoral scholar will undertake detailed analyses of seismic data in regions of active injection with the broad goal of understanding and mitigating the hazard due to injection-induced seismicity. The candidate would be free to use existing data sets, or to collect new data. Should the candidate choose to collect new data (or supplement existing data sets) one advantage to installing instruments around a hydraulic fracture well would be that the short time span of operation would allow the postdoc to actively participate in data collection and almost immediately begin data analysis. Applications are due Feb. 17, 2015. For additional information and to apply, please see the Research Opportunity announcement RO#15-7 at http://geology.usgs.gov/postdoc/opps/research.html. Please contact Elizabeth Cochran (ecochran@usgs.gov) and Rebecca Harrington (rebecca.harrington@mcgill.ca) if you are interested this opportunity.

2.
THE HIGH-RATE REVOLUTION: STUDYING TECTONIC DEFORMATION AT PREVIOUSLY INACCESSIBLE TEMPORAL AND SPATIAL SCALES.
We seek a postdoctoral Fellow to study fault slip processes using new types of instrumentation and methods of analysis that measure ground deformation on time scales rarely sampled previously, from fractions of a second to hours. In particular, strainmeters, GPS receivers, tiltmeters, and pressure sensors record with sampling rates as high as 20 Hz or more and have increased the dynamic range of measureable deformation by orders of magnitude, so that we can address key questions about how earthquakes and aseismic slip scale over the full spectrum of source sizes. Specific project topics may relate to earthquake source process studies, transient aseismic slip, as well as studies to better understanding of the measurements themselves. The Fellow's home office would be at the USGS’s Seattle field office, at the University of Washington. Applicants must have a Ph.D. or an equivalent degree, preferably with some expertise in geodesy and tectonics. Research Advisors include Joan Gomberg (USGS Earthquake Hazards Program, Seattle WA); Evelyn Roeloffs ((USGS Earthquake Hazards Program, Vancouver WA); David Schmidt (University of Washington); Jeff McGuire (Woods Hole Oceanographic Institute). Contact Joan Gomberg at gomberg@usgs.gov or 206-616-5581 for project information and for general program information see http://geology.usgs.gov/postdoc/. APPLICATIONS due by Feb. 17, 2015.

Post-doctoral research position investigating aseismic slip, earthquake occurrence and hazard
The USGS Mendenhall post-doctoral research program has an opportunity for research into the conditions that lead to seismic versus aseismic faulting and the spatial and temporal interaction of fault slip modes, to advance our understanding of earthquake occurrence and earthquake hazard. It is a multidisciplinary opportunity involving seismology, deformation and geodesy, geophysics, experimental fault mechanics, and seismic hazard analysis. It is open to candidates from all of these fields. Possible research topics include but are not limited to:
1) Determining the extent that areas of coseismic and aseismic slip overlap, and the implications for forecasting future large earthquake ruptures.
2) Seismologic, deformational or laboratory constraints on the physical processes underlying transient fault slip, including ETS and the occurrence of foreshock sequences.
3) Better establishing the seismic moment from co-seismic slip below the 'locked' depth, scaling of such deep slip with ruptured area and the influence of deep slip on large earthquake stress drop and surface slip.
4) Relation of episodic slow slip to large earthquake occurrence, including improved observational and rheological constraints on the up-dip extent of ETS.
5) Improved observations of transitions between aseismic and seismic slip and their relation to temperature, depth, mineralogy, phase transformations, slip rate, strain rate and pore pressure.
6) Developing methods to use geodetically observable aseismic transients or associated foreshocks in monitoring and earthquake hazard, for example in short-term likelihood forecasts.
7) Constraints on the dynamic rheology of the near-trench extent of subduction megathrusts and the mechanics of co-seismic coupling among fault slip, ground motion and tsunamigenesis.
Application deadline: February 17th 2015
Position start dates: Start dates have not been finalized. At the present time they are projected to be between May 2015 and early 2016.

Hi all,
We are organizing a session at the Annual Meeting of the Seismological Society of America, that will take place in April 2015 in Pasadena, CA.
As you can see below in the session description, we are trying to get industry, public and academic perspectives on the need for, and the usage of, earthquake research into hazard and risk assessments, be it on the methodology development side or real life business cases.
We are encouraging professionals to state what their needs are and how they incorporate earthquake research into their work.
We are encouraging researchers to present what science they think ought to be included into hazard or risk models, as well as what science they think might be of interest.
The deadline for abstract submission is January 9. Please write and submit your abstract now!
Best regards and best wishes for 2015!
Delphine Fitzenz,
Co-convener of the SSA 2015 session Earthquake Hazards and Risk: Drivers and Consumers of Earthquake Research
Earthquake Hazards and Risk: Drivers and Consumers of Earthquake Research
Early earthquake hazard models date back to the 1960’s whereas the first earthquake risk models were proposed circa the 1990’s. Both the motivation and methodologies for these models have evolved substantially since. In particular, recent advances in ground motion prediction equations, probabilistic source modeling, inventory compilation, computational engines and vulnerability studies have led to improved hazard and risk modeling advances. Yet, significant gaps and large uncertainties remain. In this session, we invite hazard and risk professionals—particularly those in the user community—to describe their challenges and their needs in this field for focused research and future products. Our hope is to motivate discussion between hazard and risk disciplines including those among academia, and practicing professionals, modelers, and the related user communities. Topics including how to address the complexity of earthquake sequences, scenario development and use, and loss and risk modeling are encouraged.
