6th IWGoRS Workshop
November 21, 2022 – November 23, 2022 in Paris, France
About the Workshop
The 6th IWGoRS workshop will be held at the Institut de Physique du Globe (IPG), Paris (near place Jussieu with hotels in the vicinity). The workshop will focus again on any aspect of gradient-related ground motion including the recording of rotations and strain, instrumentation, earthquake sources, non-standard rheologies, inverse problems, geodesy, earthquake engineering, long-period seismology, planetary seismology, array-derived rotation and strain, noise-correlation studies, ring laser technology, Earth’s rotation, seismic decoupling, problems of fundamental physics and others. Information on a detailed schedule and further organisational details will follow soon.
iXblue, and IPG Paris will sponsor the meeting. Further sponsorship is provided through the EU funded SPIN project, the PIONEERS project, and the ERC ROMY project (LMU Munich).
Thanks to the sponsoring of iXblue, LMU Munich, IPG Paris, and the EU projects ROMY, SPIN and PIONEERS there is NO registration fee. We offer two events after the end of the scientific programme Wednesday lunchtime:
1. Visit of iXblue, St. Germain-en-Laye
Visit of the Workshops and Testing Facility of the iXblue Company that developed the BlueSeis-3A rotation sensors (and many other 6C sensing systems particularly for navigation systems). The visit will start Wednesday November 23 15:00 at the iXblue Company, 34 Rue de la Croix de Fer, 78100 Saint-Germain-en-Laye. It is easy to get there from central Paris by RER A and bus/taxi (approx. 1 hour). Once you arrived at St. Germain-en-Laye share taxis to get to iXblue premises at 34 RUE DE LA CROIX DE FER. Make sure you have ID card with you!
2. Caroline Montier chante Juliette Gréco «La Femme»
As a round up of our meeting we propose you to dive into real French Chanson Culture and join us for the concert at the cosy Theatre Essaion next to the Forum les Halles et Centre Pompidou. Caroline Montier interprets chansons by Juliette Greco with her own arrangments. More info and a snippet can be accessed here. Tickets are at a reduced rate of 15$. Just go to the venue and mention the IWGoRS Meeting at the ticket office. After the concert we will visit an adjacent bar.
