Dear All,

I would like to draw your attention to the upcoming IUGG Meeting in 
Prague  22 June- July 2, 2015

S06e Strong Ground Motion: Rotational Seismology
Convener: Heiner Igel <mailto:igel at geophysik.uni-muenchen.de> (Munchen, 
Germany)
Co-conveners: Ana Ferreira (London, U.K.), Johana Brokesova (Charles 
University Prague, Czech Republic)

Scope: Seismology is no longer based only on the analysis of 
observations made with classical seismometers measuring translational 
motions or their time derivatives. More and more observables like 
strain, rotations, GPS-based measurements, and others are used to 
constrain either the Earth’s structure or to understand the nature of 
seismic sources and observed ground shaking. The analysis of rotational 
ground motions has recently emerged as a new branch in seismology and 
earthquake engineering. Rotational motions have several implications: 1) 
depending on frequency and amplitude range translational seismometer 
records are contaminated by rotational motions; 2) when both motion 
types (or additional strain measurements) are available the collocated 
records contain direct information on subsurface structure; 3) the 
additional motion components can contribute to the excitation of 
structures and structures can radiate additional rotational motions; 4) 
rotational motion observations can help in decomposing seismic wave 
fields; 5) inverse problems for structure and source may benefit from 
these additional observables. We invite contributions on any aspects of 
direct or indirect (array-based) measurements, interpretation, or 
theoretical aspects of rotational ground motions, and progress in 
rotation sensor development.

Abstract Submission deadline: January 31, 2015!

Regards
Heiner Igel
