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





Session ID#: 23314

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.
