Description
Digitized seismograms and event catalogues from a small observatory that recorded 22 thousand earthquakes, most of them too faint to feel.
Provenance
Sent to Lazarus by post, with a note asking whether anything could be saved. The tape was sticky with binder breakdown and was baked at low temperature before a single careful read. Reassembled from fragments spread across several carriers.
