Webinar (100 seats available only!):

*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.
