Scanarray-a broadband seismological experiment in the baltic shield
Under embargo until: 2022-05-05 The ScanArray international collaborative program acquired broadband seismological data at 192 locations in the Baltic Shield during the period between 2012 and 2017. The main objective of the program is to provide seismological constraints on the structure of the lit...
