In the years 1912 and 1917, during the first world war two explosions took place in the eastern part of Austria in an ammunition depot. Observations of infrasound signals were made in the close vicinity of the depots as well at distances of between 250 and 300 km. Old documents and reports describing both incidents are kept in the archive of the Zentralanstalt für Meteorologie und Geophysik (ZAMG). A compilation of the historic data will be shown in the presentation.
