The National Institute of Geophysics and Volcanology, INGV, is enriched with a new database on line relating to the orientations of the active effort field in Italy.
For the first time active stress data is available through a database called IPSI Italian Present day Sbraid Iindicators, accessible directly from the INGV website.
These are original and partly revised data that have undergone a thorough scientific evaluation process before being included in this database.
All data were analyzed with standard criteria in order to make them comparable with similar data on a global scale. Today the database contains 855 data, updated to December 2015, relating to information on the state of crustal stress up to a maximum depth of 40 km, grouped into the following main categories:
- breakout along the deep bores
- focal mechanisms
- active fault data
The data, all georeferenced, as well as being available online, can be downloaded in different formats and used for further processing.
These data are also part of the international project World Stress Map.

THEMSELVES database"Italian Present day Sbraid Indicators", is a georeferenced repository of information on the crustal present-day stress field maintained at INGV. It consists of horizontal stress orientations analyzed and compiled in a standardized format and quality-ranked for reliability and comparability on a global scale. Nowadays the database contains 855 data records updated to December 2015.
IPSI collects information of the Italian contemporary crustal stress, within the upper 40 km of the Earth's crust, from different stress indicators grouped in the following main categories:
- Borehole breakouts
- Earthquake focal mechanisms
- Active fault-slip data
The users can download the dataset in different format.
Italian data are part of the World Stress Map
