Short summary
Two moderate earthquakes near Mirotice (Bohemian Massif) in 2024 and 2025 were analysed using seismological and crowdsourced macroseismic data. Both events occurred at unusually large depths (22–24 km) and were widely felt. Non-circular macroseismic patterns reflect tectonic control and contrasting attenuation between different tectonic units and constrain subvertical structures within the Bohemian Massif. Normal faulting matches the regional stress field, suggesting deep structural control.

Bottom trawling is a fishing method that disturbs the seafloor and affects marine ecosystems. This study conducted experimental trawling and monitored biogeochemical changes over three weeks. Results showed reduced nutrient and alkalinity fluxes, decreased benthic carbon respiration, and disrupted biogeochemical processes. While the decline in alkalinity had only a minor effect on atmospheric CO2, the study highlights the lasting ecological impacts of bottom trawling.

We compare seismometers with the 6C method, which combines rotational and seismometer data, determining signal directions and wave velocities for short and continuous low-frequency volcanic signals at Mt. Etna. Either the cluster or the rotational sensor reliably detect continuous signal directions, aligning with the observatory data. For short signals, 6C directions deviate more, likely due to a complex underground. Combining both methods' velocity results improves understanding volcanic waves.

This study analysed marine sediment samples from areas with and without minimal hydrocarbon seepage from reservoirs underneath. Depth profiles of dissolved chemical components in the pore water and molecular biological data revealed differences in microbial community composition and activity. These results indicate that even minor hydrocarbon seepage affects sedimentary biogeochemical cycling in marine sediments, potentially providing a new tool for the detection of hydrocarbon reservoirs.

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.

We assessed the performance of permutation entropy (PE), phase permutation entropy (PPE), and instantaneous frequency (IF), which are estimated from a single seismic station, to detect changes before, during, and after the 2014–2015 Holuhraun eruption in Iceland. We show that these three parameters are sensitive to the pre-eruptive and eruptive processes. Finally, we discuss their potential and limitations in eruption monitoring.

We use uncrewed-aerial-system-derived optical and infrared data, mineralogical and geochemical analyses of rock samples, and surface degassing measurements to analyze degassing and hydrothermal alteration at the fumaroles of the La Fossa cone, Vulcano island, Italy. We give a detailed view of associated structures and dynamics, such as local alteration gradients, diffuse active units that significantly contribute to the total activity, or effects of permeability reduction and surface sealing.

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.

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.

Rock cores down to 2250 m depth, groundwater-bearing fractures, and drilling fluid were sampled for DNA to characterize the subsurface microbial community. In general, microbial biomass was extremely low despite the employment of detection methods widespread in low-biomass environments. The described contamination control measures could support future sampling efforts, and our findings emphasize the use of sequencing extraction controls.

Investigation of the global Earth's structure benefits from the analysis of ocean bottom seismometer (OBS) data that allow an improved seismic illumination of dark spots of crustal and mantle structures in the oceanic regions of the Earth. However, recordings from the ocean bottom are often highly contaminated by noise. We developed an OBS noise reduction algorithm, which removes much of the oceanic noise while preserving the earthquake signal and does not introduce waveform distortion.

We present a unique catalogue of more than 5100 highly accurate seismic moment tensors of earthquakes that occurred in West Bohemia, Czech Republic, in the period 2008–2018. The catalogue covers a long period of seismicity with several prominent earthquake swarms. The dataset is ideal for being utilized by a large community of researchers for various seismological purposes such as for studies of migration of foci, spatiotemporal evolution of seismicity, tectonic stress, or fluid flow on faults.

The Collisional Orogeny in the Scandinavian Caledonides project provides insights into the deep structure and bedrock of a ca. 400 Ma old major orogen to study deformation processes that are hidden at depth from direct access in modern mountain belts. This paper describes the successful operations at the second site. It provides an overview of the retrieved geological section that differs from the expected and summarises the scientific potential of the accomplished data sets and drill core.

The rapid decline of the Dead Sea level since the 1960s has provoked a dynamic reaction from the coastal groundwater system, with physical and chemical erosion creating subsurface voids and conduits. By combining remote sensing, geophysical methods, and numerical modelling at the Dead Sea’s eastern shore, we link groundwater flow patterns to the formation of surface stream channels, sinkholes and uvalas. Better understanding of this karst system will improve regional hazard assessment.

The Alpine mountains are known for a complex tectonic history. We shed light onto ongoing tectonic processes by studying rupture mechanisms of small to moderate earthquakes between 2016 and 2019 observed by the temporary AlpArray seismic network. The rupture processes of 75 earthquakes were analyzed, along with past earthquakes and deformation data. Our observations point at variations in the underlying tectonic processes and stress regimes across the Alps.

Short summary
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.
