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.

This paper describes data and preliminary analyses made by the INGV emergency task force EMERSITO, devoted to site effects and seismic microzonation studies, following the November 9th, 2022, MW 5.5 earthquake (Adriatic sea, Italy). Considering the earthquake affected area, EMERSITO deployed a temporary seismic network of 11 stations (net code 6N) sampling different geological units in the urban area of Ancona, the regional capital of Marche, and operated from November 2022 to February 2023.

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.

We present the first determinations of the Fe oxidation state of tiny spinel inclusions (<40 µm) in olivine from a wehrlitic lapillus collected at Mt. Vulture (Italy) via in situ synchrotron Mössbauer spectroscopy. These data, along with the chemistry of olivine and (rare) orthopyroxene, allowed us to calculate the logfO2 of the wehrlitic sample. This study opens the possibility to retrieve the redox state of mantle xenoliths using the Fe3+ / ∑Fe and chemistry of spinel inclusions in olivine.

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.

We study time-varying vertical deformation signals in the European
Alps by analyzing GNSS position time series. We associate the deformation
signals to geophysical forcing processes, finding that atmospheric and
hydrological loading are by far the most important cause of seasonal
displacements. Recognizing and filtering out non-tectonic signals allows us
to improve the accuracy and precision of the vertical velocities.

The Venetian Southern Alps (Italy) are located in a slowly deforming plate-boundary region where strong earthquakes occurred in the past even if seismological and geomorphological evidence is not conclusive about the specific thrust faults involved. In this study, we integrate and model different geodetic datasets of ground velocity to constrain the seismogenic potential of the studied faults, giving an example of the importance of using vertical geodetic data for seismic hazard estimates.

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.

We present a first application of seismic attributes, a well-known technique in the oil and gas industry, to vintage seismic reflection profiles in a seismotectonic study. Our results improve data interpretability, allowing us to detect peculiar geophysical signatures of faulting and a regional seismogenic layer. We suggest a new tool for both seismotectonic research and assessments of the seismic hazard, not only in the central Apennines (Italy), but also in seismically active areas abroad.

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.

We integrated geological and geophysical data to study the evolution of a large sector of the central Apennines, in Italy. The adopted approach permitted us to cast light on timing of faults activity over the past about 2 million years. The results we obtained has implication in terms of assessment of seismic sources of strong earthquakes. In particular, we defined which of the investigated faults are able to produce large-magnitude seismic events and which are no longer able.

We describe here the contribution of Istituto Nazionale di Geofisica e Vulcanolgia (INGV) to the AlpArray Seismic Network (AASN) in the framework of the AlpArray project (http://www.alparray.ethz.ch), a large European collaborative research initiative.
The aim of AlpArray is carrying out cutting edge research to advance our understanding of the deep structure, geodynamics, tectonics and seismic hazard of the greater Alpine area (Alps-Apennines-Carpathians-Dinarides orogenic system).

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.
