Dear Colleagues,

We would like to draw your attention to our SSA session "Theoretical and methodological innovations for 3D/4D seismic imaging of near-surface, crustal, and global scales". In this session, we will discuss novel approaches for 3D and time-lapse imaging in variety of scales.

As invited speakers, we are happy to have Roel Snieder (Colorado School of Mines).

Please go to the SSA webpage (https://www.seismosoc.org/meetings/2017/absub/) to submit your abstract. The deadline is January 11.

Please find the detailed session description below.


Best regards,

Session Description:
This session will focus on recent theoretical and methodological developments of seismic imaging and monitoring (i.e., time-resolved imaging) techniques to better understand the Earth´s structure on various scales. In previous years, imaging techniques have developed rapidly thanks to the advent of high-density networks, new modeling techniques, and unprecedented computation capacities. This includes, for example, seismic noise surface wave tomography, accurate estimation of source locations of microseismic events, and full-wave inversion with active/passive sources. However, significant problems, both well-known and lesser-known, remain. These include model resolution, uncertainty, reproducibility, nonlinearity, and non-uniqueness.
We invite novel approaches for solving common practical problems for 3D/4D imaging. To this regard, we welcome innovations and advances in physics-based imaging, 3D/4D tomography, waveform tomography, new migration techniques, advanced signal processing, multi-component seismic noise correlations, monitoring and locating of velocity changes, and joint inversion of multiple geophysical observations. Presentations of ideas to overcome effects of structure outside the modeled region, uneven ray coverage, and limitation of resolution will be also included in this session. Studies that compare real-Earth results obtained using different methods, and assess repeatability, are particularly encouraged as well as methods to establish best practice for the proper implementation of synthetic reconstruction tests.
