A Directory for the Discovery of Legacy Seismic Data
Legacy seismic data is an important primary data set of observations of seismic events that occurred in the past century. Using new methods and applying new insights and discoveries, careful reuse of these data has furthered our understanding of seismogenic processes. However, much of this data remains undiscoverable to a generation of digital seismologist. Accessing physical seismograms from collections often requires retrieval from hard to access facilities. In recent years, recognition of the fragile state of many collections and the emphasis on FAIR data has led to a renewal in efforts to preserve these collections digitally for future use. Efforts are underway to establish minimal metadata and best practices for the preservation of these growing collections. However, to be FAIR, the data not only need to be open licensed and available, they must also be discoverable.
To aid researchers in the discovery of legacy seismic data, we have created a directory that provides information about available resources. The goal is to assist in the discovery and access of legacy seismic data collections worldwide. Legacy seismic data is any data related to the operation of seismic networks that were not collected originally in digital form. This includes seismograms, station bulletins, phase cards, among other artifacts. The initial stage of the project focuses on seismogram collections originally recorded on paper but can include data recorded on other media such as FM tape. We present information from publicly available sources about seismograms that are available in digital format typically as digital images. Interactive maps show available data by station, event, and managing organization and provide a starting point to access additional information on the resource as well as references in the literature. In building a community for FAIR legacy data, we seek contributions and feedback in developing this open-source project as a valued community-maintained resource.
