Abstract

Knowledge of the present-day tectonic stress is essential for numerous applications in petroleum exploration and production and in civil and mining engineering, such as improving the stability of boreholes and tunnels and enhancing petroleum production through natural or induced fractures. The World Stress Map (WSM) Project is a collaborative project between academia, industry, and government that is building a comprehensive global database of present-day stress information to better understand the state and sources of contemporary tectonic stress in the lithosphere (Figure 1).

The World Stress Map consisting of more than 10 500 A-C quality stress indicators from a variety of stress measurement techniques. NF = normal faulting stress regime (red). SS = strike-slip (green). TF = thrust fault (blue). U = undefined (black). See legend for more details on symbols. All data and maps are freely available on the WSM Web site: www.world-stress-map.org.
