Seize the Digital Age with Analog Seismograms

Seismologists have long recognized the need to preserve and share seismic data. Concerns for the preservation of analog data spans decades of preservation efforts including early efforts to photograph images of seismograms to media such as microfiche and more recently scanning records as digital images. Seismograms, derived data such as phase data, and station metadata have historically been shared through seismological centers or by direct exchange between researchers. With the arrival of continuous digital recordings in the 1990s, came an explosion of data just at the birth of the internet age. Today, these seismic data are readily available democratizing the access to information. However, analog data remains difficult to Find, Access, and Reuse. Recent efforts to increase the use of historical data focuses on its findability with necessary metadata. Empowering researchers to find and (re)analyze these data will increase our ability to make connections across Earth systems to drive discovery.
