World Stress Map Project co-labeled as a legacy item of the International Year of Planet Earth

The International Union of Geodesy and Geophysics (IUGG) nominated with the support of the International Lithosphere Program (ILP) and the Commission for the Geological Map of the World (CGMW) as project of the International Year of Planet Earth (IYPE). This nomination has been approved and accepted by Eduardo de Mulder, the Executive Director of the IYPE secretariat. In August 2009 the WSM project became officially the co-label as an legacy item of the International Year of Planet Earth (IYPE).

World Stress Map Project transferred to the GFZ Potsdam

From 1996-2008 the World Stress Map was a research project of the Heidelberg Academy of Sciences and Humanities located at the Geophysical Institute of the Universität Karlsruhe (TH). In January 2009 the project has been transferred to the Helmholtz Centre Potsdam - German Research Centre for Geosciences GFZ. The future of the WSM project is secured as the GFZ Potsdam has agreed to incorporate the WSM into its research structure and will provide resources for maintaining and further developing it. The WSM service and the open access politics remains unaffected by this transfer.

World Stress Map database Release 2008

Thanks to the efforts of the international community of researchers, the WSM 2008 database release contains 21,750 data records (see statistics). The 5781 new data records came either direct contact with individual researchers, publications or catalogues. Furthermore, numerous data records have been revised. In particular we would like to acknowledge the following collegues for their individual contributions: Gulam Babayev, Rima Chatterjee, Cecilia Guzman, Tobias Hergert, Marek Jarosinski, Rosalind King, Tanja Kühler, Katrin Plenkers, Marcel Thielmann, John Townend, and Nino Tsereteli.

WSM Database in Google Earth

With Google Earth we can use a modern platform to get a very fast and detailed view on the WSM 2008 database release. Besides the SH orientation and the color coded tectonic regime the Google Earth visualization contains the plate boundaries from Bird (2003). Furthermore, with a mouse click you will get detailed technical information for the data record of interest. Provided you have installed Google Earth, download the WSM database in Google Earth format here and simply drag and drop the file into an open Google Earth window.

Update of the quality assignment

In collaboration with a number of international experts and intense internal discussion we provide an updated version of the quality ranking scheme. Major changes were that we splited the quality ranking for focal mechanisms solutions in three sub-categories. We also distinguish not breakout analysis from caliper and image logs as the latter have a quality. For further information, please click here.

New guidelines for stress data analysis

In collaboration with a number of international experts we provide new guidelines for breakout analysis from image logs, for focal mechanisms solutions, and for overcoring data. For further information, please click here.

New version 2.0 of CASMI - Create A Stress Map Interactively

CASMI v2.0 is an open-access software tool for the generation of stress maps. It has a graphical user interface and is the stand-alone counterpart of CASMO, but with a wider range of functions. CASMI includes the WSM 2008 database. Besides the addition of the new release we extended the filter options in particular for the single focal mechanisms (FMS). We also made implemented the smoothing algorithm of Müller et al. (2003) for the bipolar stress data. For further information, please click here.
