Description
In recent years, the seismological community has recognized the critical importance of preserving analogue seismic data. However, Germany was lacking strategies for preserving these records. Here we present the preliminary findings of our feasibility study, which evaluates the potential for digitizing all analogue seismic data in Germany.
Initial inventory of the contents of German analogue seismic data archives was successfully conducted. Information was gathered from 12 German institutions and compiled into a consolidated database. This database has been published to provide extensive insights into data collections.
Furthermore, we designed and run test to estimate the workload associated with scanning and digitizing seismic records. We collected paper seismograms from three different seismic stations over three separate one-month periods, along with metadata. These records were scanned using a variety of techniques.
Subsequently, we vectorized the data using two distinct tools and compared the outcomes.
Additionally, we analyzed a test event (Tsar Bomba, 1961) to evaluate methods for determining earthquake source parameters from digitized analogue data.
Every stage of the digitization process was precisely documented, forming a manual of guidelines that serves as a foundation for establishing a long-term strategy for preserving and digitizing analogue seismic records in Germany.
