The Italian Present-day Stress Indicators (IPSI) database is a freely available Italian georeferenced repository of information regarding the crustal stress field. It consists of horizontal stress orientations that have been analysed, compiled in a standardised format and quality-ranked for reliability and comparability on a global scale. The database contains a collection of information regarding contemporary stress within the shallow crust from the following main stress-indicator categories: borehole breakouts; earthquake focal mechanisms; seismic sequences and active fault-slip data. The present database (IPSI 1.4) released in January 2020 is accessible through a web interface which facilitates findability, accessibility, interoperability and reusability of the dataset. Moreover, it contains 928 records updated up until December 2019 with an increase of 10% with respect to the first one, and improved metadata information. The uniform spread of stress data over a given territory is relevant for earth crustal modelling or as starting point in many applied studies. It is therefore necessary to continue collecting new data and update present-day stress maps to obtain more reliable evaluations.
意大利现今应力指标（IPSI）数据库是一个免费提供的意大利地理参考信息库，用于地壳应力场。它包含已分析的水平应力方向，以标准化格式进行编译，并在全球范围内对可靠性和可比性进行质量排名。该数据库包含有关浅层地壳内当代应力的信息，主要来自以下主要的应力指标类别：钻孔破裂；地震震源机制；地震序列和活动断层滑动数据。本数据库（IPSI 1.4）于 2020 年 1 月发布，可通过网络界面访问，便于数据集的可发现性、可访问性、互操作性和可重用性。此外，它包含截至 2019 年 12 月的 928 条记录，与第一个版本相比增加了 10%，并且元数据信息得到了改进。在给定区域内均匀分布的应力数据对于地壳建模或许多应用研究的起点都很重要。因此，有必要继续收集新数据并更新现今的应力图，以获得更可靠的评估。
