Abstract

The German Seismological Broadband Array (DSEBRA) comprises 100 mobile seismological stations, which are currently contributing to the multidisciplinary international AdriaArray project, launched in 2022 to comprehensively study the Adriatic plate and its surrounding regions. The data collected in this project enable detailed monitoring of seismic activity and imaging of the crustal and upper mantle structures in the Central Mediterranean. DSEBRA stations are deployed across a wide range of geographical locations, including the Alpine foreland of Germany and Austria, the high Alps of Austria, the Pannonian Basin in Hungary, the southern Dinarides in Montenegro, Kosovo, and Albania, North Macedonia, as well as the mainland of Greece. Equipped with state‑of‑the‑art technology and featuring innovative station design and remote monitoring capabilities, these stations enable the acquisition of high‑quality data in near real‑time, which is essential for early warning systems in this seismically active region. In this study, the noise characteristics of the stations are analyzed in both the frequency and time domains, revealing significant variations that can be attributed to differences in geographical and geological settings, as well as levels of urbanization. In the frequency range of the secondary microseisms, a split in the double frequency peak is observed at the Balkan stations. This split is attributed to the simultaneous activation of two distinct source regions in the surrounding oceans. This article provides an overview of the distribution and performance of DSEBRA stations within the AdriaArray project. The contribution of DSEBRA to AdriaArray underscores the importance of well‑equipped station pools and international collaboration in achieving the scientific objectives of large‑scale seismic networks.
