Welcome to SHINE

This web-based application, in few and rather simple steps, calculates the maximum horizontal stress orientation (from now on SHmax) of the present-day stress field for any point on the Earth’s surface. SHINE interpolates data records from regional or global dataset. For information on SHmax measurements and their tectonic meaning, please refer to structural geology texts or to the World Stress Map website.

With SHINE we aim to address three major issues that have previously not been resolved simultaneously in any SHmax interpolation algorithm: the scatter in SHmax orientations, the uneven sampling of stress data, and the correlation of stress orientations with distance. SHINE applies the method described by Carafa and Barba (2013), which modified and extended the clustered data analysis technique used by Bird & Li (1996).

SHINE website and its code have been developed (and are being updated), maintained and supported by INGV and its project FIRB Abruzzo (code: RBAP10ZC8K_003).

We warmly encourage the use of SHINE and will be happy to hear your experience with it or hear about any possible bugs that you might encounter during its use. As we are interested in growing and further developing SHINE, we'll be happy to hear your suggestions at

Scientific ethics and courtesy require the appropriate acknowledgment of results obtained through SHINE in any publication, report, study or work by citing Carafa et al., 2015 for the SHINE application and Carafa & Barba, 2013 for the interpolation method theory.

SHINE authors distance themselves from any responsibility arising from the improper use of data and methodology/algorithm. If any damage occurs from the use of SHmax orientations obtained through SHINE, only the user carries all liability.

Enjoy SHINE!
