Dear Colleagues,

We would like to draw your attention to our session "3D/4D Seismic Imaging and Their Interpretation for Seismic Hazard Assessment" at the 2018 SSA/LACSC meeting in Miami, Florida, on May 14-17, 2018. In this session, we invite theoretical and methodological novel approaches of seismic imaging and monitoring, as well as their applications for seismic hazard assessment. The detailed session description is attached below.

Please go to the SSA webpage (https://www.seismosoc.org/meetings/abstract-submissions/) to submit your abstract. The deadline of the submission is January 24.

Session conveners:
- Marco Pilz (GFZ Potsdam)
- Nori Nakata (University of Oklahoma)

Best regards,
Nori

Session Description:

Thanks to the recent development of imaging and monitoring techniques, we can obtain much higher spatial resolution of subsurface structures and/or time-lapse changes of them. In previous years, imaging and monitoring techniques have developed rapidly due to the advent of high-density networks, new modeling techniques, and unprecedented computation capacities. In addition to using them for interpreting subsurface geology and mechanics, such 3D/4D structural information is useful for modeling and interpreting high-frequency seismic waves or understanding the dynamic behaviors of structures, both of which are important for seismic hazard assessment.

In this session, we would like to cover both theoretical and methodological aspects as well as novel approaches for solving common practical problems for 3D/4D imaging and monitoring. We welcome contributions for the interpretation of obtained structural information for seismic hazard assessment such as ground motion prediction, more accurate estimation of earthquake magnitude and moment tensor, and understanding the near-surface nonlinear effects. We further encourage abstracts focusing on multiscale imaging applications which involve novel processing such as higher-order correlations, double beamforming, multi-dimensional deconvolution, nonlinear optimization techniques, machine learning and large-scale data analysis or very dense receiver array analysis. Presentations related to amplitude extraction, attenuation, higher-mode Rayleigh/Love waves, body waves or usage of multi-component signals are also encouraged.
