UNIBRA/DSEBRA: The German Seismological Broadband Array and Its Contribution to AlpArray—Deployment and Performance

Abstract

Abstract The German Seismological Broadband Array (Deutsches Seismologisches Breitband Array [DSEBRA]) comprises 100 mobile seismological stations and can be deployed as a stand-alone network or in conjunction with other stations to build an even larger array. The first mission of DSEBRA was in the framework of the European AlpArray initiative. The aim of the project is to understand the deep structure, mantle dynamics, plate tectonics, its linkage to surface processes, and seismic hazard of the Alps–Apennines–Carpathians–Dinarides orogenic system. DSEBRA, purchased in the framework of the German Priority Program Mountain Building Processes in 4D, contributed to one-third of the temporary AlpArray seismic network (AASN). The stations are currently deployed in the Alpine foreland of Germany and Austria, in the high Alps of Austria and Italy, and in the Pannonian basins of Hungary. The stations are equipped with state-of-the-art technology, thus allowing to acquire high-quality broadband data in real time. In this article, we present the current station deployment within the AASN, describing the equipment and its handling. Furthermore, we discuss the data quality and perform noise analyses. In conclusion, DSEBRA stations provide excellent data and are very well suited for deployment in national or international seismological experiments.
