Since more than 40 years ago, WEGENER has brought together geoscientists who want to collaborate on the application of space and terrestrial geodetic techniques to the study of geodynamics in the Alpine–Mediterranean plate boundary region.

During the past decade, WEGENER has broadened its scopes beyond the Mediterranean and Geodesy. This led to the creation of a new Seismo-geodesy sub-commission, jointly supported by the International Association of Geodesy (IAG) and International Association of Seismology and Physics of the Earth’s Interior (IASPEI).

WEGENER, through meetings organized every two years in and around the Mediterranean is now an important component, offering a space for collaborative discussion and research projects.

The 20th WEGENER Assembly 2023 will be organized by the National Office of Mines (ONM which is the Geological Survey of Tunisia) from 24 to 27 October 2023 in Sousse, Tunisia. The ONM has shown a substantial interest in the processing of GNSS data and the geodynamic study of Tunisia since 2019.

**20th WEGENER Key points**

**The 20th Assembly of Wegener aims to gather geo-scientists and share recent progress in space geodesy (GPS and InSAR) and knowledge in seismo-geodesy, deformation of volcanic fields.
**A special attention will be devoted to the implications for the seismic hazard and risk reduction to foster discussion and new proposals for joint research projects
**It will take place on 24–27 October 2023 in Sousse, Tunisia.
**It will go ahead in person but there will be a possibility to present online.
**It will feature keynotes, panels and oral / E-poster sessions.
**Abstract submissions (max. 350 words) will be accepted until 31 May 2023.
**We encourage submissions of research works from all regions of the world.
**Read more about the covered themes and sessions which will be organised (see Sessions)
**Before submission, please read the Guidelines.
**The 20th WEGENER Proceedings will be published in Springer ASTI Series (indexed in Scopus & SCImago). However, publishing in the proceedings in optional.
**Best papers will be published in special issues of some reputable journals (special issues).
