The World Stress Map (WSM) is a global compilation of information on the crustal present-day stress field maintained since 2009 at the Helmholtz Centre Potsdam GFZ German Research Centre for Geosciences in the Section 2.6 Seismic Hazard and Stress Field. It is a collaborative project between academia and industry that aims to characterize the crustal stress pattern and to understand the stress sources. The WSM commenced in 1986 as a project of the International Lithosphere Program (ILP) under the leadership of Mary-Lou Zoback. From 1995-2008 it was a project of the Heidelberg Academy of Sciences and Humanities headed by Karl Fuchs and Friedemann Wenzel. Since 2012 the WSM is a member of the ICSU World Data System. All stress information is analysed and compiled in a standardized format and quality-ranked for reliability and comparability on a global scale. The current new WSM database release 2016 contains 42,870 data records within the upper 40 km of the Earth’s crust.

The WSM is an open-access public database and is used by various academic and industrial institutions working in a wide range of Earth science disciplines such as geodynamics, hazard assessment, hydrocarbon exploitations and engineering. The main operational areas are:  

  • Reservoir characterization and management
  • Stability of mines, tunnel, boreholes and waste disposal sites
  • Calibration of geomechanical-numerical models
  • 4D Thermo-Hydro-Mechanical (THM) models
  • Hazard assessment e.g. by means of fault-slip tendency analysis

World Stress Map 2016 | The stress map shows the orientation of maximum horizontal stress SHmax in the Earth's crust (Heidbach et al., 2016). Symbols denote the SHmax orientation from various stress indicators. Colours denote the stress regime: normal faulting (NF), strike-slip (SS), thrust faulting (TF) and unknown (U).
