Chain of custody

A private compilation of publicly archived seismic records, assembled by a retired engineer over nine years and given to this newspaper without condition. Every underlying record is public and we have spot-checked forty of them against the archive. Four did not match; the compiler agreed, corrected them, and the corrected version is the one we hold.

Held by: They Buried, document room; underlying data public

Excerpt

EVENT 1971-284-A · long-period · duration 3h 51m · no clear P/S separation
  compiler's note: ringing persists far beyond the model for a body of this
  composition. This is well documented and has ordinary explanations. I am
  not proposing an extraordinary one. I am only listing the events.

Transcribed by the data desk. Line breaks follow the original. Bracketed matter is ours.

Editor's note

MERIDIAN's 1994 covering letter mentions lunar seismology. Every story citing this document therefore carries our funding disclosure. See Ownership & Funding.
