Rotation and Strain in Seismology - Applications, Instrumentation and Theory

Session ID#: 81294

Session Description:
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, 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 correcting seismometer recordings for dynamic tilt.

We invite contributions on any recent development in the fields of applications, instrumentation, and theory for observing rotational motion and strain. 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.
