What It Is

HV.DEVL volcanic tremor during 2018 Kilauea eruption --- harmonic tremor at 100 sps, quasi-periodic with complex amplitude modulation, narrowband (IRIS CC0)

Interpretation

Standard analysis sees: red spectrum (low-frequency / 1-over-f power); time-irreversible (sharp rises, slow decay). The atlas additionally detects Spectral Analysis:spectral_slope.
