About IWGoRS:

The International Working Group on Rotational Seismology (IWGoRS) intents to promote, plan and share scientific investigations covering all degrees of freedom of the seismic wave field by extending conventional translational recordings with observations of strain and rotations.  These additional observables, enabled by new instrumentation has implications “for related fields” such as,


IWGoRS furthermore intends to share experience, data, software, and results in an open Web-based environment.

In addition, to disseminate information on all matters pertaining to rotational motions through publications and by holding meetings and workshops, and to interact with professional bodies in engineering and science. A provisional charter containing the goals, structure, and task groups of IGWoRS is available.
