Description
Digitized seismograms and event catalogues from a small observatory that recorded 10 thousand earthquakes, most of them too faint to feel.
Provenance
Deposited by Red River Libraries, which had held it unread for years. The drive spun up and was imaged behind a write blocker in a single pass. Independent reads agree bit for bit.
