Dear Colleagues,
We want to draw your attention to the following 2023 SSA Annual Meeting session:
Crustal Imaging of High Seismic Hazard Regions

In this session, we aim to gather contributions from passive and active-source seismic studies that discuss the characterization of crustal structures. We welcome contributions based on gravity and magnetic data, velocity and attenuation tomography (t* method, direct wave attenuation, coda waves), and other imaging techniques (e.g., using ambient noise and converted waves). Studies that include tomographic models and other multidisciplinary geophysical and geological data in ground motion modeling, seismic hazard assessments and site response analysis are welcomed. We also encourage submissions from early-career researchers and studies using innovative methodologies (e.g., machine learning).

The full session description is included below.
Please consider submitting your abstract to our session before the deadline on January 11, 2023.

We look forward to seeing you in Puerto Rico.
Kind regards,

Session Description:
In high seismic hazard areas, imaging both the elastic and anelastic properties of the medium is key for evaluating deformation processes and the impact of complex fault systems on ground motion amplification. Characterizing crustal features is especially challenging when wave focusing and conversions, or fluid interactions occur such as in geothermal and volcanic areas. Combining attenuation and velocity models is crucial for predicting site response and seismic wavefield amplitudes. This session aims at providing an overview of techniques and applications related to the imaging and validation of seismic velocity and attenuation across various scales ranging from laboratory samples to basin and plate boundary scales. We welcome onshore and offshore passive and active-source seismic studies and studies based on gravity and magnetic data that discuss the characterization of crustal structures, including faults, volcanic and geothermal areas. We aim to gather contributions from velocity and attenuation tomography (t* method, direct wave attenuation, coda waves) and other imaging techniques (e.g., using ambient noise and converted waves). We welcome studies aimed at including these models and other multidisciplinary geophysical and geological data in ground motion modeling, seismic hazard assessments and site response analysis. We also encourage submissions from early-career researchers and studies using innovative methodologies (e.g., machine learning).
