What It Is

2013 Okhotsk M8.3 (depth 598 km) P-wave at ANMO --- sharp impulsive onset, minimal coda, 20 sps broadband vertical (IRIS CC0)

Interpretation

Standard analysis sees: left-skewed; smooth / autocorrelated; red spectrum (low-frequency / 1-over-f power); time-irreversible (slow rise, sharp collapse); volatility-clustering (bursty); nonstationary / drifting. The atlas finds no named structure, but the source is distinctively extreme on Wasserstein:self_similarity (-2.6z) — beyond what the standard bank predicts for it.
