S008/S012/S014 - Observation of Rotation, Strain, and Translation in Seismology: Applications, Instrumentation, and Theory

Tuesday, 8 December 2020

Recent advances in seismic instrumentation have made direct observation of the complete seismic
wave field possible, including rotation, strain and the spatial gradients of the wave field. This is
opening new applications in various disciplines such as seismic exploration, strong motion, volcano
seismology, ocean bottom seismology, earthquake engineering and planetary exploration.
Collocated observations of translation, strain and rotation have shown great potential in, for
example, retrieving information on wave propagation directions and subsurface velocity, separating
seismic phases, and retrieving static displacements and rotations.
We invite contributions on any recent development in the fields of applications, instrumentation,
and theory for observing seismic ground rotation, strain and translation. These may include - but are
not restricted to -alternative technologies for seismometers (e.g., optical technologies), fiber-optic
technologies, such as fiber-optic gyroscopes or distributed acoustic sensing, high-frequency GPS,
and array based methods. We strongly encourage contributions on data analysis techniques,
instrument performance testing and experimental field studies.
