Plain Language Summary
Just as power banks store energy or artificial lakes store water for later use, depleted hydrocarbon reservoirs are used to store gas for later exploitation. Underground gas storage (UGS) is needed to optimize the distribution system and balance near‐constant production/distribution flows with variable market demand. It also...

In August 2021, an extremely productive seismic sequence took place in northeastern Italy. Within 1 month, we identified and localized 407 microearthquakes in the area monitored by the local Collalto Seismic Network. This is about 20 times the average monthly rate of events detected in the last decade; 92% of them are clustered near the village of...
The detection level of a seismic network is a measure of its effective ability to record small earthquakes in a given area. It can vary in both space and time and depends on several factors such as meteorological conditions, anthropic noise, local soil conditions—all factors that affect the seismic noise level—as well as the quality and operating c...
Seismic monitoring in areas where induced earthquakes could occur is a challenging topic for seismologists due to the generally very low signal to noise ratio. Therefore, the seismological community is devoting several efforts to the development of high-quality networks around the areas where fluid injection and storage and geothermal activities ta...

We analysed the instrumental seismicity in a sector of the Po Plain (Italy) to define the baseline for seismic monitoring of a new underground gas storage plant that will use the depleted gas reservoir of Cornegliano Laudense, near Lodi. The target area – a square approximately 80 km × 80 km wide – is commonly considered aseismic. The analysed peri...
The application of earthquake recordings to the estimation of an event’s magnitude and the construction of rapid-response ground-motion maps requires an adequate classification of the recording stations in terms of their site response. For permanent stations, this information can be obtained from a sufficiently large database of past recordings.

Underground fluid injection and extraction is able to change pore fluid pressure at depth and make faults unstable, due to friction-force reduction, with an increased possibility of triggering earthquakes. Studying the local seismicity, down to microearthquakes, and stress field in areas where such activities are developed are essential steps to di...

Annual monitoring of the seismicity recorded by the seismometric network of northeastern Italy managed by the National Institute of Oceanography and Experimental Geophysics – OGS. Year 2017
The site characterization in terms of the frequency‐dependent amplification of the ground motion is one of the main topics in engineering seismology. The generalized inversion technique (GIT) is a well‐established approach to evaluate the local amplification from the seismic records acquired during a seismological deployment. However, the implement...

We estimate the Mw values of 1823 weak earthquakes (Mw≤4.0) that have occurred in northeastern Italy, an area with complex tectonics and moderate seismicity, using the method proposed by Atkinson et al. (2014). The Mw is obtained from the response spectra (SAs) at 1.0 s and 0.3 s, which have been properly corrected for path effects. After tuning a...

A stable and reliable estimation of the energy released by the seismic events is a fundamental step to understand the dynamic of the source processes even for earthquakes of small sizes recorded by local networks. In the case of seismic networks devoted to monitoring human activities carried out underground, such as oil/gas production, gas storage...
Underground gas storage is one of the industrial activities capable of inducing earthquakes and its development in areas of high seismic risk may cause anxiety among people. The need of working as close as possible to safety conditions becomes the minimum requirement to carry out such operations, which are crucial for the energetic policy of an ind...
The epistemic uncertainty in ground-motion prediction can be reduced with the aid of numerical modeling of seismic waves propagation. In this work we show how a good knowledge of the geological structure can be turned into quantitative site-specific features of the ground motion by means of High Performance Computing (HPC) tools for the numerical c...

One of the most critical problems affecting seismological data acquisition is related to possible misorientation of three-component seismic sensors. This generally happens when their orientation cannot be measured directly, as in the case of sensors deployed in boreholes. We describe here the sensor reorientation procedure of the Collalto Seismic N...
The seismic hazard resulting from seismicity induced by human activity is not yet
regulated in Italy. The presence of a significant natural seismicity complicates the
differentiation of events possibly induced by human activity from ordinary natural
seismicity, while it stimulates a comparison between the ground motion that can be
expected due to t...
