Shear-wave splitting data base

We want to faciliate the overview of existing shear-wave splitting measurements and share the results of the analysis and experiments with everybody.

GoogleEarth Screenshot Please feel free to search the database.
To add your own measurements you need a password which can be obtained by writing a short email to Thank you for your understanding.
For entering your data we prepared a browser interface. Please have a look at our Preview

We provide two different output formats of the database, text files of splitting parameters and references and the database in GoogleEarth format

Important notice: The SplittingDataBase is an open-access database. It contains SKS splitting parameters, but also all the corresponding article references. So, do not forget to cite the proper works & references in your publications when using and extracting data from this base.

If you use the data or maps in publications please cite the SplittingDataBase using the following reference:

Wüstefeld, A.; Bokelmann, G. H. R.; Barruol, G.; Montagner, J.-P. (2009) "Identifying global seismic anisotropy patterns by correlating shear-wave splitting and surface waves data" , Phys. Earth Planet. Int, 176 (3-4), 198-212, doi:10.1016/j.pepi.2009.05.006 (database available online at

We recommend SplitLab to perform your splitting processing!

To easily plot the SKS splitting results with GMT4, you can use the script draw_splitDB.txt kindly provided by Frederik Tilmann (GFZ Potsdam).

We have also prepared a some other useful datasets for
(you need GoogleEarth4.0.2080 or later)
