Imaging Science Workshops for USArray

点击翻译按钮获取中文摘要

We are proposing a series of 3 workshops to be held over three years focusing on the subjectof scattered wave imaging using earthquakes recorded by densely spaced broadbandseismograph arrays, and particularly using the USArray data. The workshops will be organizedby a steering committee, and developed in cooperation with the participating scientists as theseries progresses. The workshops will be advertised broadly and will be open to anyoneinterested in attending.The workshops will be designed to accelerate the development of scattered wave imagingtechniques by creating a virtual center of scientists and students. The virtual center will activelyengage scientists and students involved in this research in a working forum for exchange ofideas, joint development of software, and exchange of field and synthetic datasets. Workshopand study topics will include 1) investigation of the effects of the approximations used informulating imaging algorithms on the final images, 2) testing and validation of differentimaging methods using field and synthetic data, 3) experiment design criteria, 4) seismic velocityanalysis, and 5) relating the images to composition and physical state of the Earth.The workshops will be designed to include working classes for graduatestudents (and senior scientists) involved in this research area. This will build community in thenew generation of young scientists who are emerging as the next group of theoretical leaders inseismology, and who will reap the benefits of the Earthscope endeavor. The synergy of bringingpeople from academic and industrial backgrounds will advance the field more rapidly than ispossible otherwise. This improved communication will help advance knowledge in both theacademic and industrial research communities and enhance cross-fertilization between thesegroups.
