Description
Digitized seismograms and event catalogues from a small observatory that recorded 33 thousand earthquakes, most of them too faint to feel.
Provenance
Transferred from the backlog of unread media at a partner archive. Read once, slowly, on a restored drive. A second pass was not attempted. All of the work survives. The repairs are listed in the record’s damage map.
