We invite contributions on recent developments in the area of instrumentation, analysis, and applications for ground based geodetic and seismic observables. The session focusses on three subtopics:

Recently, alternative technologies for seismometers (e.g., optical technologies), instruments for observation of inertial rotations based on any physical principle (e.g. optical Sagnac interferometry, atom interferometry, etc.), tilt, strain, and gravity measurements as well as high-frequency GPS become accessible. We strongly encourage contributions on experimental, low-power, low-budget as well as very wide dynamic range and high sensitivity solutions.

Ground translation, strain and rotation:
The recent developments on new instruments, combined with classical seismic and strain sensors, provide new ground motion observations. Here, next to theoretical advances related to wavefield gradient analysis new applications such as source and structure studies, wavefield analysis, structural engineering, and exploration geophysics are presented.

Seismic networks performances
The number and quality of seismic stations and networks in Europe continuously improves. Nevertheless, there is always scope to optimize their performance. This includes all aspects of seismic network installation, operation and management, site selection, equipment testing and installation, planning and implementing communication paths, policies for redundancy in data acquisition, processing, and archiving and integration of different datasets, including GPS and OBS.
