EGU 2022 Session on Seismic Wavefield Gradients | Tue, 24 May

There will be a session for rotational seismology at EGU GA 2022, called:
Direct observation of seismic wavefield gradients – a new approach to seismic experiments
Tue, 24 May, 17:23–18:30 (CEST) Room -2.16
Convener:          Felix Bernauer
Co-conveners:  Stefanie Donner, Conor Mow-Lowry, Céline Hadziioannou
 

New developments in seismic instrumentation enable highly precise direct point observations of seismic ground motion and its spatial gradients not only in permanent but also in temporary seismic experiments. Considerable improvements in optical and atom interferometry enable new concepts for inertial rotation, translational displacement and acceleration sensing.

Applications of the resulting new type of data range from seismic source and wavefield characterization with single point observations in harsh environments to the correction of tilt effects, e.g. for high performance seismic isolation facilities.

We invite contributions on novel measurement techniques and experiment design, on theoretical advances to the seismic wavefield gradient analysis, as well as on all aspects of applications of ground motion gradient observations in seismology, geodesy, planetary exploration, gravitational wave detection and fundamental physics.
