Abstract
The tectonics of the Adriatic microplate is not well constrained and remains
controversial, especially at its contact with the Dinarides, where it acts as the
lower plate. While the northern part of the Adriatic microplate will be accu-
rately imaged within the AlpArray project, its central and southern parts de-
serve detailed studies to obtain a complete picture of its structure and evolution.
We set up the Central Adriatic Seismic Experiment (CASE) as a AlpArray
Complementary Experiment with a temporary seismic network to provide high-
quality seismological data as a foundation for research with state-of-the-art
methods and high-precision seismic images of the controversial area. The inter-
national AlpArray-CASE project involves four institutions: the Department of
Earth Sciences and the Swiss Seismological Service of ETH Zürich (CH), the
Department of Geophysics of the Faculty of Science at the University of Zagreb
(HR), the Republic Hydrometeorological Service of the Republic of Srpska (BIH)
and Istituto Nazionale di Geofisica e Vulcanologia (I). The established temporary
seismic network will be operational for at least 18 months. It combines existing
permanent and temporary seismic stations operated by the involved institutions
together with newly deployed temporary seismic stations, installed in November
and December 2016, managed by ETH Zürich and INGV: five in Croatia, four
in Bosnia and Herzegovina and one in Italy. We present our scientific aims and network geometry as well as the newly deployed stations sites and settings. In
particular, the new stations show favourable noise level (power spectral density
estimates). The new network improves considerably the theoretical ray coverage
for ambient noise tomography and the magnitude threshold shown in the Bayesian magnitude of completeness threshold map.
