Summary:

The
youth of seismology as a science, compared to the typical duration of
seismic cycles, results in a relative scarcity of records of large
earthquakes available for processing by modern analytical techniques, which
in turn makes archived datasets of historical seismograms extremely
valuable in order to enhance our understanding of the occurrence of large,
destructive earthquakes. Unfortunately, the value of these datasets is not
always perceived adequately by decision-making administrators, which has
resulted in the destruction (or last-minute salvage) of irreplaceable
datasets.

We present a quick review of the
nature of the datasets of seismological archives, and of specific
algorithms allowing their use for the modern retrieval of the source
characteristics of the relevant earthquakes. We then describe protocols for
the transfer of analog datasets to digital support, including by
contact-less photography when the poor physical state of the records
prevents the use of mechanical scanners.

Finally,
we give some worldwide examples of existing collections, and of successful
programs of digital archiving of these valuable
datasets.
