Stress Data of the WSM


World Stress Map database

The WSM is the global database of contemporary tectonic stress of the Earth's crust. Its uniformity and quality is guaranteed through:

  • quality ranking of the data according to international standards
  • standardized regime assignment

The WSM merges data which otherwise would be fragmented in separate, often inaccessible archives. It provides the long-term preservation of tectonic stress data from physical loss of data carriers or organizational problems of data storage.

Types of stress indicators

In the World Stress Map different types of stress indicators are used to determine the tectonic stress orientation. They are grouped into four categories:

  • Earthquake focal mechanisms
  • Well bore breakouts and drilling-induced fractures
  • In-situ stress measurements (overcoring, hydraulic fracturing, borehole slotter)
  • Young geologic data (from fault-slip analysis and volcanic vent alignments)

For more details about the stress data, the structure of the database, and the access to the data please select the respective submenu. If you want to create your own stress map please use our online software tool CASMO. Since the WSM is an open-access, non-profit project we always need your support. Your contribution of new stress data is needed in order to extend the database. For more details on our contribution policy, please go to the submenu contributions.
