CIG/QUEST/IRIS Joint Workshop on Seismic Imaging of Structure and Source
Workshop SummaryThe July 14-17, 2013, workshop, hosted by the University of Alaska at Fairbanks, presented theoretical developments and applications in computational seismology with regard to earth structure and earthquake sources.
The sessions were:
- The forward problem: Model construction, meshing, and wavefield simulations
- Structure inversion
- Source modeling
- Challenges and frontiers for seismology
The formal discussion topics were:
- Tomographic model validation and uncertainty estimation
- Source modeling
- Workflows, big data, and exascale seismology
The first computing tutorial session featured the wave propagation code AXISEM and the workflow toolkit ObsPy. Participants were able to run the codes themselves and interact with the developers. The second computing tutorial featured the wave propagation code SPECFEM3D and the associated hexahedral meshing software GEOCUBIT. The workshop was strengthened by diverse geographic representation and professional representation from industry, national labs, and academia. One theme of the meeting is that we are faced with great theoretical, computational, and data-centered challenges regarding seismic imaging of earth structure and in the estimation of uncertainties.

University of Alaska, Fairbanks. Housing for the workshop will take the form of apartments, which each contain two rooms. We will organize rooming lists, and will try to match roommates to the best of our ability.
Accommodation will be covered for workshop participants for the nights of July 14, 15, 16, 17. If you would like to stay in UAF accommodation on days before or after, then you will need to make the arrangements yourself (and pay yourself). To do this, please fill out the Conference Reservation Form and email it to email@example.com and cc Camille Linn (firstname.lastname@example.org). Be sure to state that you are participating in the CIG-QUEST-IRIS workshop, so that you are billed only for nights besides July 14, 15, 16, 17. UAF conference servicies will try to provide the same room as the one for the workshop, so that you do not have to move.
Fairbanks, Alaska is serviced by Fairbanks International Airport. Attendees traveling from Europe and supported by QUEST may want to consider the Condor Airlines direct flights between Frankfurt and Fairbanks. Participants who choose to arrive earlier cannot receive reimbursement for non-conference days. International travelers not sponsored by QUEST would be required to fly on US-based airlines, or their international code-sharing partners, as part of the Fly America act, for any reimbursement. In addition, reimbursement is only allowed for coach class travel, not economy plus or other classes.
Airport to Campus transportation
The UAF campus is about three miles from the airport. The best option is to take a taxi to UAF Office of Residential Life located in Moore-Bartlett-Skarland Hall, 732 Yukon Drive. This office is open 24 hours in the summer for check ins. Please check website spreadsheet to consolidate rides.
Abstract Submission is Closed.
Poster boards are 8 ft wide by 4 ft tall. Participants who wish to pay to have their posters printed at Geophysical Institute can make arrangements directly with Design Services.
Speakers will be fully covered, either through QUEST funds or CIG. There will be some funds available for reimbursement of air and ground transportation for attendees presenting posters. Apartment housing and catering will be paid by sponsors, but not hotels. Forms will be made available to all qualified participants at the workshop to request reimbursement. Please provide a reasonably accurate estimate of your estimated costs (not including hotels) when submitting your registration form, so that we can provide an estimate of reimbursement.
The computing tutorials will be held in a computer lab maintained by Arctic Region Supercomputing Center. Participants are encouraged to bring their laptops, which can also be used to access the tutorials.
