Scientific Technical Report 16-01 WSM quality ranking scheme, database description and analysis guidelines for stress indicator / Научно-технический отчет 16-01 Схема ранжирования качества WSM, описание БД и рекомендации по анализу показателя стресса

The World Stress Map (WSM) compiles information of the contemporary crustal stress using a wide range of very different stress indicator which can be 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)
A detailed description of the stress indicator in the context of the WSM project can be found in Zoback and Zoback [1991], Zoback et al. (1989), Zoback and Zoback [1980], and Sperner et al. [2003]. A more general overview of tectonic stress and stress indicator can be found in review publications and standard text book [Bell, 1996; Engelder, 1992; Jaeger et al., 2007; Ljunggren et al., 2003; Schmitt et al., 2012; Zang and Stephansson, 2010; Zoback, 2010; Zoback, 1992]. An alternative grouping of the stress indicator using a technical perspective is presented in Fig. 1.1-1
