Dear Colleagues,

we would like to draw your attention to the following session at the
AGU Fall Meeting 2017:

S008: Ground Translation, Strain, Rotation: Using Wavefield Gradients
for Seismic Applications

Session Description:
Substantial recent progress in seismic instrumentation and array
technology has opened new roads in using wavefield gradients, strain,
and rotation for several seismic applications. Collocated recordings of
translation, strain, and rotation provide access to subsurface velocity
information, improve the resolution of source inverse problems, help
separating seismic phases, and provide information on propagation
directions. In addition – due to the sensitivity of classic broadband
seismometers to tilt – high quality measurements of ground rotations
can remove the ambiguities of horizontal ground motion measurements for
example for ocean-bottom recordings or recordings of long-period
signals on volcanoes. In this session we invite papers on new
developments of seismic instrumentation to access gradient information
(e.g., rotation sensors), small scale array measurements and analysis,
and applications such as imaging, source inversion, wavefield
reconstruction, instrument correction, single station observations in
planetary seismology and theoretical developments.
