Description
Digitized seismograms and event catalogues from a small observatory that recorded 3 thousand earthquakes, most of them too faint to feel.
Provenance
Found during a house clearance in Birchford Harbour and passed to Lazarus. The disks had been stored beside a loudspeaker, and one track on each was weak. All of the work survives. The repairs are listed in the record’s damage map.
