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.

The STAR project set out to drill 6 shallow holes and use geophysical logging to figure out the best depth for placing seismometers and strainmeters, to image the upper crust and 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 literature with what we find underground, giving solid information on rock properties, which helps understand the first couple hundred meters of the Earth's crust.

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.

Geologists can decipher the past climates and thus better understand how future climate change may affect the Earth's complex systems. In this paper, we report on a workshop held in Longyearbyen, Svalbard, to better understand how rocks in Svalbard (an Arctic archipelago) can be used to quantify major climatic shifts recorded in the past.

There are periods in Earth’s history when huge volumes of magma are erupted at the Earth’s surface. The gases released from volcanic eruptions and from sediments heated by the magma are believed to have caused severe climate changes in the geological past. We use a variety of volcanic and climatic tracers to assess how the North Atlantic Igneous Province (56–54 Ma) affected the oceans and atmosphere during a period of extreme global warming.

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.

Knowledge about physical properties at depth is crucial to image and understand structures linked with orogenic processes. We examined seismic velocities from core and downhole data from the COSC-1 borehole, Sweden, and calibrated our results with laboratory measurements on core samples. Despite a strong mismatch between the core and downhole velocities due to microcracks, mafic units are resolved at all scales, while at sample scale, strong seismic anisotropy correlates with the rock foliation.

The northeast Atlantic encompasses archetypal examples of volcanic rifted margins. Twenty-five years after the last ODP leg on these volcanic margins, the reasons for excess melting are still disputed with at least three competing hypotheses being discussed. We are proposing a new drilling campaign that will constrain the timing, rates of volcanism, and vertical movements of rifted margins.

Mercury anomalies in sedimentary rocks are used to assess whether there were periods of elevated volcanism in the geological record. We focus on five sites that cover the Palaeocene–Eocene Thermal Maximum, an extreme global warming event that occurred 55.8 million years ago. We find that sites close to the eruptions from the North Atlantic Igneous Province display significant mercury anomalies across this time interval, suggesting that magmatism played a role in the global warming event.

A scientific borehole planning workshop sponsored by the International Continental Scientific Drilling Program convened in early 2020 at Cornell University in the NE United States. Cornell plans drilling to test the potential to use geothermal heat from depths of 2700–4500 m and rock temperatures of 60 to 120 °C to heat its campus. The workshop focused on designing companion scientific projects to investigate the coupled thermal–chemical–hydrological–mechanical workings of continental crust.

The Newberry Deep Drilling Project (NDDP) will be located on the Newberry Volcano, Oregon, USA, at an idle geothermal exploration well, NWG 46-16, drilled in 2008, 3500 m deep and 340–374 °C at bottom, which will be deepened another 1000 to 1300 m to reach 500 °C. The main goals are to test EGS in the ductile/brittle transition zone and to test technology for drilling, well completion, and geophysical monitoring in a very high temperature environment.

Short summary
This contribution highlights a combined research effort to collect a combined core and down-borehole geophysics data set on two boreholes from the main island on Hawaii. The results represent one of the most complete data sets of fully cored volcanics with associated borehole measurements, which can be confidently matched directly between remote data and core. The data set and results of this study include findings which should enable improved borehole facies analysis through volcanic sequences.
