We present new data on the orientation of fractures, their fill, and their density around the Alpine Fault, a plate boundary fault on the South Island of New Zealand. Fractures < 160 m of the fault are filled and show a range of orientations, whilst fractures at greater distances (< 500 m) are open and parallel to the rock's mechanical weakness. We interpret the latter fracture set to reflect near-surface processes, whilst the latter are potentially linked to deep-seated Alpine Fault seismicity.

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.

In this study, we use cosmogenic-sourced 3He to determine the eruption ages of 23 lava flows at Mt Ruapehu, Aotearoa New Zealand, and we show how this method can help overcome challenges associated with traditional dating methods in young lavas. Comparison with other methods demonstrates the accuracy of our data and the method's reliability. The new eruption ages allowed us to identify periods of quasi-simultaneous activity from different volcanic vents during the last 20 000 years.

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.

We revised the conceptual model of the Solfatara magmatic-hydrothermal system and we used new geothermometers and geobarometers, specifically calibrated for the Solfatara fluids, to monitor temperature, T, and total fluid pressure, P, in three distinct reservoirs at different depths, over ~40 years. The T, P changes in the intermediate reservoir (at 2.7–4 km depth) are of utmost interest because its pressurization-depressurization acts as the “engine” of bradyseism currently affecting the area.

We identified and quantified the effects of H2S on CO2 and CH4 concentrations and their respective isotopic compositions using a Picarro instrument model G2201-i. This interference was used to develop a new method to accurately quantify H2S concentrations with a G2201-i. Measuring CO2, CH4, and H2S concentrations in the gas phase within 20 minutes using a single instrument will significantly improve current analytical routines and has the potential to be a powerful tool for volcano monitoring.

At the end of an Arctic winter, we found ponded water 500 m under a glacier. We explored the chemistry and microbiology of this unique, dark, and cold aquatic habitat to better understand ecology beneath glaciers. The water was occupied by cold-loving and cold-tolerant microbes with versatile metabolisms and broad habitat ranges and was depleted in compounds commonly used by microbes. These results show that microbes can become established beneath glaciers and deplete nutrients within months.

We present an innovative approach to study halogen chemistry in the plume of Masaya volcano in Nicaragua. An unique data set was collected using multiple techniques, including drones. These data enabled us to determine the fraction of activation of the respective halogens at various plume ages, where in-mixing of ambient air causes chemical reactions. An atmospheric chemistry box model was employed to further examine the field results and help our understanding of volcanic plume chemistry.

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.

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.

This short communication presents an efficient method for analyzing large fault scarp data sets. The programs and workflow required are open-source and the methodology is easy to use; thus the barrier to entry is low. This tool can be applied to a broad range of active tectonic studies. A case study in the Taupo Volcanic Zone, New Zealand, exemplifies the novelty of this tool by generating results that are consistent with extensive field campaigns in only a few hours at a work station.

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.

Three new cored boreholes through Surtsey volcano, an isolated island in southeastern Iceland, provide fresh insights into understanding how explosive submarine volcanism and the earliest alteration of basaltic deposits proceed in a pristine oceanic environment. The still-hot volcano was first sampled through a drill core in 1979. The time-lapse drill cores record the changing geochemical, mineralogical, microbiological, and material properties of the basalt 50 years after eruptions terminated.

Geothermal resource is heat energy that can be recovered from underground in the Earth. As part of the European H2020 GEMex project, 3D geological models were constructed for the geothermal sites of Los Humeros and Acoculco in Mexico. These models allow a better understanding of the rock types and structure when targeting deep sources of geothermal energy; they will be updated during the project, serving as a framework for simulating the geothermal system.

Portable cavity ring-down spectrometers (e.g. G1101-i) for isotopic CO2 have an interference with elevated (higher than ambient) amounts of hydrogen sulfide (H2S). This results from the overlap of the H2S and CO2 spectral lines in the near-infrared, causing changes in both the 12CO2 and 13CO2 concentrations. This effect can be removed by reacting H2S with a metal scrub before analysis, which will facilitate the application of these instruments in H2S-rich environments (i.e. active volcanoes).

The 5158 m deep borehole of the Chinese Continental Scientific Drilling (CCSD) Project in the Sulu ultrahigh-pressure metamorphic terrain marked the starting point of the CCSD Program. Since then, several continental scientific drilling projects were conducted with funding of the Chinese government and partially with support of ICDP, resulting in a total drilling depth of more than 35 000 m. This paper reviews the history and major progress of the CCSD Program in the past 15 years.

Short summary
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.
