Short summary
We built six observatory stations in central Italy to monitor a fault potentially capable of generating a strong earthquake. Each site has 80–160 m deep wells equipped with strainmeters and seismometers. At the surface, we placed GNSS antennas and seismic and meteorological sensors. All data, which are open access for the scientific community, will help us to better understand the complex physical and chemical processes that lead to the generation of the full range of slow and fast earthquakes.

This study presents a new geological model of the Fano-Pesaro offshore area, refining its tectonic framework. We identified multiple fault detachments at different depths, influencing thrust system dynamics and deformation. This work highlights the importance of integrating seismic and borehole data, even legacy, to build reliable subsurface models. These findings contribute to improved seismic hazard assessment and support offshore energy development and carbon storage projects.

Volcanoes where tectonic plates drift apart pose eruption and earthquake hazards. Underground waters are difficult to track. Underground microbial life is probably plentiful but unexplored. Scientists discussed the idea of drilling two boreholes in the Okataina Volcanic Centre, New Zealand, to unravel the connections between volcano, faults, geotherms, and the biosphere, also integrating mātauranga Māori (Indigenous knowledge) to assess hazards and manage resources and microbial ecosystems.

The newly established geodynamic laboratory aims to develop modern, comprehensive, multiparameter observations at depth for studying earthquake swarms, crustal fluid flow, mantle-derived fluid degassing and processes of the deep biosphere. It is located in the West Bohemia–Vogtland (western Eger Rift) geodynamic region and comprises a set of five shallow boreholes with high-frequency 3-D seismic arrays as well as continuous real-time fluid monitoring at depth and the study of the deep biosphere.

Short summary
The STAR project set out to drill six shallow holes and use geophysical logging to find the best depth for placing seismometers and strainmeters to image the upper crust, in particular the Alto Tiberina fault, Italy. These measurements give us a better idea of what the rocks are like, helping us connect what we know from the literature with what we find underground, giving solid information on rock properties, which helps us understand the first few hundred meters of the Earth's crust.
