Short summary
During the COVID-19 pandemic lockdown, the city of Barcelona was covered by a network of 19 seismometers. The results confirm that the quieting of human activity during lockdown has resulted in a reduction of seismic vibrations. The different lockdown phases in Barcelona are recognized consistently at most of the seismic stations. Our contribution demonstrates that seismic noise can be used as a free and reliable tool to monitor human activity in urban environments.

Seismic data provide critical information about the structure of the lithosphere, and their preservation is essential for innovative research reusing data. The Seismic DAta REpository (SeisDARE) comprises legacy and recently acquired seismic data in the Iberian Peninsula and Morocco. This database has been built by a network of different institutions that promote multidisciplinary research. We aim to make seismic data easily available to the research, industry, and educational communities.

We integrated petrophysical and travel-time tomography data to refine the velocity model of a legacy seismic profile from the Limerick Syncline, a geologically complex Zn-Pb district in southwest Ireland. The improved seismic imaging enhanced subsurface characterisation and revealed previously unrecognised structural features, contributing to a better geological understanding and supporting future mineral exploration.

Sediments are like history books for geologists and geophysicists. By studying them, we can learn about past environments, sea level and climate changes, and where the sediments came from. To aid in understanding the geology, georesources, and potential hazards in the Iberian Peninsula and its surrounding seas, we present the SedDARE-IB sediment data repository. As an application in geothermal exploration, we investigate how sediment thickness affects the depth of the 150 °C isotherm.

The AGEMERA project (Agile Exploration and Geo-Modelling for European Critical Raw Materials) enhances EU critical raw materials exploration by integrating non-invasive methods such as ambient noise passive seismic, drone-based surveys, and muography. These technologies map bedrock properties and resource distribution effectively, feeding data into a comprehensive web-based repository for strategic analysis.

Short summary
We assess the capability of multiple methods based on the interpretation of seismic noise to map the basement of the Cerdanya Basin, located in the eastern Pyrenees. Basement depth estimations retrieved from the different approaches are consistent, with maximum depths reaching 700 m close to the Têt fault bounding the basin to the east. Our results prove that seismic noise analysis using high-density networks is an excellent tool to improve the geological characterization of sedimentary basins.
