What It Is
1940 Imperial Valley NS strong motion --- the most-studied earthquake record in structural engineering
Interpretation
Standard analysis sees: time-irreversible (sharp rises, slow decay). The atlas detects no named structure beyond this. It sits beside EEG Eyes Closed in the atlas (standard-bank rank 38) — a neighbor conventional features miss.

What the atlas adds
Nothing beyond the standard reading — this source’s structure is already captured by standard features; the atlas adds no named residual.
